Testing CBD oil using my TCheck Potency Tester

Comparing the potency of WINK CBD Oil compared to a batch of my Green Witch CBD oil using my TCheck device.


  1. What strength rating is listed on your 2 different oils from the manufacturer’s? Are your test results close to the listed ones? Thank you 😊 I’m very happy to see people are now getting their TCheck devices…can’t wait to get mine.
