Absolute excellence in terms of their customer service. I had my Higrade Scope stolen and they without hesitation were able to replace it for me, they are sending me a new one. It's very very much appreciated as the scope cost me 80$. 100% recommend!!!

#1HearterUSA | 8/31/2020

Money Well Spent!!!!

I LOVE my HiGrade camera🤗 Use it all the time and it always says the same thing as Leafly!!

HollY WooDUSA | 8/23/2020

I buy medical grade marijuana from the dispensary in Colorado that has the THC percentage labeled on the bag, and every time I test what I have with high grade it is within .5% of what they say it is. Very impressed.

Manuel RodriquezCanada | 8/7/2020

After giving this product a bad review I must say after doing further investigating this product is actually ON POINT and worth the investment. Technical support is awesome !!! 👍👍⭐⭐⭐⭐⭐💫

Cory bettisUSA | 8/2/2020

Wasnt sure about it at first..but gotta say I'm a firm believer in this little thing. Price could be better but overall happy with the results

Kevin OttyUSA | 7/25/2020

Honestly probably the best little investment I made. Very accurate with THC % and very helpful with diagnosing problems with your plants and a full step by step guide on how to fix your plant.

lil deno!Canada | 7/23/2020

Hi grade

Great product and is working wonders,very happy with purchase! Gives same results every time if you re test

Philip BrinkleyUSA | 7/20/2020

I've been using it to check if my dispensary is selling me bump or not so far it's matching up with what the packaging says it's supposed to be and I've done this with other dispensaries too so to kudos to the creator of this app

tyron smithUSA | 7/15/2020

They’ve got their algorithms pretty close to dialed in, of course it is dependent on the quality and location of the sample pictures you take. The science and accuracy of the quality/potency testing seems to be solid. I've tested 20 strains and all 20 came back close if not spot on accurate On the Growers side of the app, since thats what actually counts, they have a team that will email you back with basic grow knowledge and suggested course of action. They have helped me pretty good.

troy maynneUSA | 7/10/2020

Perfect product

I love this device a lot no cap especially for my plants it works just how I imagined it would and better hope everyone else has the same experience I did🙏🏼🎉

Arnold LoweUSA | 7/5/2020

I love it! The growers help with plant issues is great. The assist in my harvest timing also is a plus.....trugfarmer10151

Dave FortenbacherCanada | 6/27/2020

I am surprised at how well it gauged the THC and accuracy.

GreencureCanada | 6/27/2020

Wow

I am a cultivator on a state licensed farm and can I tell you this app has helped us with so many issues we were running in to without knowing. We highly suggest practicing vocationaly for our new hires with this app and lense to really learn from experts. 5/5 can't wait to see the future of this app.

verotinkerbellUSA | 6/26/2020

This is Awesome!!!!!

I just got it in the mail today and I’ve been playing around with it, its been super easy. I have some bud that I got at the dispensary Stardawy and it was accurate 21% THC. This is pretty cool, when you just want to make sure what you’re buying is what’s in the container. highly recommend it, will give it away as presents for sure!

scottylikesbudUSA | 6/7/2020

Finally

Finally a microscope and ai joined to test thc on plants, is your dispensary claiming super high thc levels? Well put them to the test, results may surprise you. I just got mine today. Can not wait to test the local dispensary claims lol I have a feeling that this is going to paint a different picture then there actual advertised labels. Need faster response, would be nice getting a message from an actual person letting you know that the grow questions was received and being looked into. Like idk add a chat feature for contacting the people giving out advice? Overall revolutionary app. If this continues to go as is I can see how this can be the next big thing for cannabis testing. If it catches on So I tested some dispensary bud. First test, 26% look at thc label and get this it is 26.95% first test outlook looking good. Love it. Please contact the 420magazine.com staff. Many home growers on that website. I am one of many,new growers. So I think that website would be best for marketing to growers. All 157,000 of them. Contact teddy Edwards on the site. And if all goes well, remember your friend scottylikesbud for introducing your company’s to one another. If this works well, (I have a feeling it will) Updated, Is this kit also good for measuring thc content in sugar leaves? If so is there a way to do so? Or can it be done in the future?

Kenny PUSA | 6/4/2020

App works well for me so far. Really digging this app right now. Very useful on all fronts on cannabis especially with the scope.

New 2 GoogleCanada | 4/21/2020

Boom!

Yep. Worth the $80 Just got it 5 minutes ago. Works awesome and precise and consistent

jeffro_rulzUSA | 4/19/2020

Neat app

This is kinda cool, although I’m not sure on the accuracy. I still enjoy it and would recommend to any serious cannabis connoisseurs.

Chief Keef Sosa LennUSA | 4/12/2020

High grade for HiGrade!!!

Great for testing THC % of buds!!! Not to mention tips for growing!!! Great product and app!!!

TLW420USA | 3/25/2020

Great instrument to have!

This thing is great! Gives you real time data almost spot on with results! I’m hooked and will be using it from here on out! It’s really about the app! But either way I love it!

unknown purposeUSA | 12/25/2019

I like it I purchase the app to check drug dealer weed and I'm kind of curious about my own weed. It seems legitimate for just taking pictures I think it's pretty damn close

HardnoxxcultivationUSA | 12/22/2019

Way cool!

I am so excited as well for ur cbd and hemp testing as I own a hemp farm in North Carolina

won't zoom inUSA | 12/22/2019

Fun to see the thc levels instantly

It seems to have different results per strain. I like it.

GDP_55USA | 12/22/2019

Works great!

Works exactly as advertised. And I’d say it’s quite accurate from what the thc ratings compared to what the cannabis clubs list as. Have only once had it significantly off. And the weed honestly didn’t look as high rated as they had it listed. But coulda have been from the bottom buds. So many variables. But this this is very accurate!

Toot5353USA | 12/21/2019

Good JoB

Works Great love the product!!!!!!!

DenwotegGermany | 12/20/2019

Meega good idea, and really well implemented just a little expensive for a stoner 😅 For the possibilities but fair I think.

Le GulFrance | 12/18/2019

Bon achat

Après avoir acheté un microscope de poche à 20 euros ou je me suis rendu compte qu’il fallait prélever (ramené au magasin), je suis tombé sur cette loupe *45 adaptable sur portable pour 60 euros, rien que ça c’est déjà un bon achat, mais avec le service en plus qui me sert pour savoir quand récolter c’est vraiment bien, réponse très rapide (15mn mes deux dernières demande). Seul bémol, l’anglais lol, Google traduction m’aide pour communiquer avec le service. Je conseil sérieusement cette application surtout si vous êtes novice comme moi et que vous voulez de bon conseil en toute discrétion...

na_joeyUSA | 12/18/2019

Awesomeness

Awesomeness

Jasper SchoonraadUSA | 12/17/2019

It's awesome and works like a dream, please update strain info to show the average percentage of indica and sativa per strain as apposed to just saying Hybrid. Adding average THC percentage for indoor/ outdoor or just an overall average like "between 18 to 25%"

Steven BlombouFrance | 12/16/2019

Excellente. Réponse rapide et précise. Apporte une grande aide

MATHEW SIEDERSUSA | 12/16/2019

very helpful app and AI there service is A1 . I have been using it for a few weeks so far and it has been pretty much spot on. I grow 3 strains and it's been very helpful with my whole grow process. looking forward to more features as the technology gets better. you guys are amazing at higrade love your product and great service provided to me so far🍻

Shikhar PunUSA | 12/16/2019

JJJ ASpain | 11/30/2019

La aplicación está de lujo y la explicaciones que te dan igual muy buenas y enviar la foto y te responde rápido y con respuestas muy muy buenas pero no le doy 5 estrellas hasta que no pongan en español la aplicación

NoMan SkyPoland | 11/30/2019

Sama aplikacja wystarczy czy trzeba jakieś urządzenie na aparat kupić??

bestthatevendoneitUSA | 11/29/2019

Five star

Seems to be okay app just joined so waiting on my kit yet but look forward to getting it to test thc % & the 24/7 grow support is what got my attention also.

flashg7379Canada | 11/28/2019

Gej StoodleyUSA | 11/28/2019

This app is it may not be 100% accurate but it is damn close I tested this with Canadian government graded weed and it came back 4*5 times spot on

NatiBass GenerationUSA | 11/21/2019

Love this app! It's going to help with false advertisement with these companies claiming 30 plus percent THC

Yep greatUSA | 11/20/2019

We love it and trust it

Very cool device, seems accurate I have tested a few known strains.

Nathan JoblingUSA | 11/17/2019

Excellent service good proof to show others of your herbal medicine and how good it is on the scale of 1/10 i Rate this at 10 stars

Mogonda79Canada | 11/16/2019

Great for home growers

Support from agronomists is worth the cost

adambates87Canada | 11/14/2019

Pretty good

Pretty cool app and very knowledgeable people behind it. It would be nice to have a little better scope but all in all its not bad. And as for the percentage reading... i find it hard to believe its accurate, but within reason (tested against dispensary) its still somewhat close. So for home growers looking to get a ballpark answer on thc testing, thats what youll get, which is better than a guess!! Some more information written up on the app about strains and growing techniques would probably be beneficial as well!

Fl MMJ Deals Snoke RUSA | 11/12/2019

So far results have been consistent with both the labelled thc as the control and using on 3 nicest nugs, preferable a cracked nug to show off the inside. I found things like photo filters, low light affects, and such can cause different thc % and quality ratings. If it's dark then light showing its bright colors it will be off.

PuzzledddUSA | 11/11/2019

Great set of 2nd eyes

This app is awesome for us home growers that are struggling with different aspects of growing. They somehow identified correctly... bug feces from a regular picture. The only reason that I am not 5 stars is room to grow, strain identification, an algorithm that helps identify what mystery seeds your friend gave you... wouldn’t that be nice to know you have gold or lousy pot. Actually, their grading of cannabis is also quite accurate. I will be an annual subscriber, don’t go jacking the price People’s!

GrowMobil GermanyGermany | 11/8/2019

Die App ist zwar noch in der Entwicklung aber der Code ist genial :)

E.J. WerewolfUSA | 11/7/2019

Consistently Great

I’ve been using this app for months now. It is dead on every time. In PA we get prepacks and it says how much THC is in the product. The app is within +\- 1 on thc percentage and is always right about the condition of the bud. It’s no surprise, this is an Israeli made apps, everything the Israelis produce is done so with excellence.

Stalker Fan #1USA | 11/6/2019

Pretty cool. Works ok

Can’t prove it 100% but it probably gets close. I’d recommend it if you need it.

Maik HeuerGermany | 11/4/2019

besser als erwartet. und ein 1a Beratungsservice welcher prompt inerhalb von ein paar Stunden antwortet. echt klasse auf jeden fall für jeden Einsteiger und jedem der mehr über sein eigen... erfahren möchte.

Dare KočarSlovenia | 11/4/2019

Res dobra applikacija po treh fotkah bule iz različnih strani ti jo oceni z zvezdicami do 5, če veš strain ti da pa več podatkov, maš pa možnost naročnine in dobiš mikroskop da vidi trikome in ti pove vsebnost thcja

I love this app. It has helped me confirm thc potency of my medicine

Blup BlupblupGermany | 11/2/2019

Nice app to test your stuff

CANNAbo$USA | 11/1/2019

Mr Grow GoodBudd

One of the best useful and cutting edge apps on the market. From it’s THC % counter to strain info and your own personal agronomist. If you’re in the Cannabis field or just an ordinary Stoner. It’s a must have and I rate it 20

Smokevicious GrowsUSA | 10/31/2019

Works great if you know how to use it properly. I suggest opening your flowers and taking the analysis from there.

William Delore BergeUSA | 10/30/2019

Easy and intuitive Ap works every time, wish there was some way to identify what strain or ...allow the grower to give it a name. Really a great tool, no serious head should be without. Price was realistic and considering a Very good deal. Delivered lightning fast. Wonderful toy..wish I had more buds to test. DO NOT HESITATE GET ONE NOW YOU WONT BE DISAPPOINTED

JarrettCanada | 10/29/2019

This thing is pretty awesome. I work at a legal cannabis dispensary in Canada and purchased 22% cannabis from my work which uses a much more sophisticated method of testing and i tested it to this and the first test came in at 22% and the second test 21% so I would say it is fairly accurate

OG Pappa PUSA | 10/28/2019

Great no more taking peoples word for it now i know great job

Bryan RichardsonSpain | 10/28/2019

I’m loving this hi grade scope and the app. Makes me feel a lot better on how I grow. I now know where I can improve

Chinoboy420USA | 10/25/2019

Works alright having troubles here and there tooken a couple pictures of some dispensary flower with 23% thc and gave around the right accuracy I give it 4

Bruce GallagherUSA | 10/25/2019

Awesome so glad I got the whole kit and not just the app. It's well worth it. ☯️🕉️💚

AntonioItaly | 10/19/2019

Ottima app per avere un idea della qualità della cannabis che si sta per assumere / comprare . Grazie al microscopio ( acquistabile separatamente ) con 3 foto si ottiene una stima del THC approssimativa del 3% . Purtroppo non ho la possibilità di confrontare i risultati con i test in laboratorio , ma sembra funzionare alla perfezione . 5 stelle meritate

Swagalilcious509USA | 10/18/2019

Great app

Really does work!!

smithsixxCanada | 9/27/2019

Pretty good

I wish the scope was a bit easier to slide onto the phone but other than that its pretty cool

Greg StrathdeeCanada | 9/27/2019

I have been testing this app and scope out on known and unknown dried samples and on growing plants in the flowering stage. So far it is quite accurate with the %THC. The growers support is decent and relatively quick to respond. As the growing plants grow to harvest I will be able to tell more about how accurate the growers advice is. The scope is quite good. It fits my galaxy so but is a tight fit. I would like to be able to edit the strain data and be able to create my own database. EDIT: I am still finding the THC% to typically be within +/-3 (usually on the higher side) compared to what the store bought product says. I am getting close to harvest and I am finding the Growers support very useful and so far seem quite accurate. They were able to identify bud rot on some of my buds. I like the new look but I would really like to have the ability to create my own database with pictures and strain notes. With the ability to enter in a strain name I have created and have it ask if this is the same strain or a new one. If I say it is the same strain than it automatically groups this data into a file containing all THC, grade, grower and strain information for that created strain.

TheWeedGodUSA | 8/19/2019

Great App

It’s a fantastic app! Perfect for those stoners that want to know how good their bud is. I wish you didn’t have to spend $$$ for the HiGrade pro. Just to find the THC% but it’s all good. Still a great app!
