Works very well
I'm on my 3rd treatment, and I'm surprised at how quickly this works!!  One of the best features for me is the LIP BALM! Its a MUST! It is what makes this item so comfortable. No burning lips or inner  mouth . Ive never had a whitening product work this well and be this comfortable.  Only CON is, I wish the battery device charged for a longer time period than it does. Must plug in right away after done using or it will not be ready the next time you want to use it. The power seems to only last long enough for the 4 8 minute sessions in one treatment. So that could be improved upon. So far I am really liking this products. It has worked quick well. Will stay posted for any further changes or reports.
