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!!!!!!!

I have used the tCheck 2 over the last two years and have found it’s a rapid way to check the concentration of different formulations. I have compared the results with 3rd party lab testing and was amazed by it’s accuracy.
Noelle
Game changer! No more guessing what my doses are. I make tinctures for friends and family and they have been extremely happy with what I have provided.

Just purchased my second Check potency tester to run more tests at once. It does an excellent job of distinguishing CBD in real bud.
