    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!!!

    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.

    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 !!! 👍👍⭐⭐⭐⭐⭐💫

    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.

    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

    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.
