  • “I can’t say enough about the tCheck device! It’s really helped me assure I’m dosing the right amount and not over or under dosing for clients. Thank you I love this device.” –Michelle

  • “Game changer! No more guessing what my doses are. I make tinctures for frineds and family and they have been extremely happw with what I have provided.” –Noelle

  • "Just purchased my second Check potency tester after a friend had to have it as soon as I showed it to them. The tester is used mostly for flower and it does an excellent job of distinguishing hemp/cbd from real bud. In our area of the US hemp being labeled as real is a normal occurence due to the easy access of hemp." - John

  • “I have used the tCheck 2 over the last two years and have found it’s a rapid, accurate way to check concentration when making different formulations. I have compared the tCheck 2 results with 3rd party lab testing and was amazed by it’s accuracy.” –Jon
