One word: FANTASTIC. I have never experienced tooth sensitivity which is amazing!! I've noticed a whiter smile in just one use!

I just love a white smile and this is it you guys it really really helped with my yellow teeth. It really did the job.

Perfect on the go whitening, easy to use and great results! I always stock up when they are on sale.

I do like the whitening strips on occasion but they do cause sensitivity for me so I cant use them all that often

I like using these to brighten my smile. I don't use it that often however because they make my teeth super sensitive

Visibly whiter after just one session! Easy to use and works so well for my teeth. Definitely recommend

Only con was it made my teeth temporarily sensitive. The whitening for the price makes it worth it. I use it once a year

This set tastes awful but you can see the difference after a couple of uses. Unfortunately it makes my teeth sensitive.

I used these for my wedding and had good results. I am not a fan of the peroxide taste or the way my teeth feel afterwards though

It does an ok job of whitening. Maybe I just have difficult teeth cos I need to do 3 strips in a week.
