No sensitivity but the device stopped working after 7 days
I have mixed reviews. The product works well and there is no sensitivity. My teeth are sensitive to cold air, and with this product I was finally able to not worry! After the third day I realized I was placing too much gel on my gums, after that I had zero sensitivity!!! The reason the product is getting three stars is because it stopped charging and working after day 7. My teeth are not as white as I had hoped they would be, but that may be due to my genetics. Honestly, I was so excited about this product not making my teeth sensitive that I might still consider getting it again. I'm worried if I do get it again and it stops working after the return period I won't be able to get my money back. The device should not have stopped working after seven days....
