My sister-in-law is a hygienist and she recommended this and the crest whitening toothpaste! The both work extremely well!

Been using these for years. They don't hurt my teeth very bad. Only a slight sensitivity after using for a few hours

Love these! They keep my teeth looking white and fight through the coffee stains that I seem to always end up with

This product is amazing , if you use it 2 times a week I promise you teeth will be so white in a month

i have tried these but they haven't worked too well. i see a small difference but not as much as i want for my teeth!

these kits usually make my teeth sensitive but these strips work really well and don't make them sensitive

I use about once a year and it keeps my teeth white all year long, and I drink coffee and red wine regularly

I've used these white strips, and to be honest I have had good results. The more you use it the better, and I really recommend it.

I constantly get compliments on my pearly whites. I use these strips probably twice a week to keep my smile sparkling! Easy to use!

These are whitening, but the taste of the gel makes me gag. And they make my teeth very sensitive. I stopped using them.
