Review (3/5): No teeth sensitivity
I was sold when it said you can just plug it into your phone! But unfortunately that didn’t work.. so I had to plug it into a regular outlet.. I’ve been using this for about 3 weeks and I do see a slight difference. Not anything dramatic but a little better than before! I didn’t get no teeth sensitivity, which is good! Hopefully after a few more treatments my teeth will look more whiter!!
