VerifiedUNI to the rescue
I've been vapin for years. Usually using a pen like battery. I was introduced to the YOCAN UNI by a friend and very quickly realized that it seemed to have a longer battery life than the pen battery. I bought a few as presents and 3yrs later still have the same blue Yocan UNI. These devices are a god send. Thank you for your product!!!
