One off the best teeth whitening out there! So easy to use and makes your teeth sparkle. I am a teeth whitener girly. This is by far one off the best.

Best on the market

People constantly ask me how my teeth are so white. These little babies is how.

I like the small box of auto ship teeth whitening strips. They are easy to use and they do a fairly decent job of getting rid of the stains and best of all they do not make my gums feel sensitive. But if you want a really white vibrant smile these are not what I would recommend. Furthermore they can be a bit of a challenge when the actual strip needs to separate from the base. You have to make sure the strips have seperated from the base and have stuck to the teeth. I would recommend if you suffer from some gum sensitivity as I have not experienced pain after using these strips.

This did not work. I wasted my hard earned $46 on this product. Used all 4 pairs of trays and saw 0 results. Absolutely 0 results. I previously used the crest whitening strip and got great results. I will go back to the crest strips. This product is absolute garbage.

4 treatment trays @ 15% and I'm happy with the results. I've done a $200 zoom whitening session before and received nearly the same results - and far less painful.I brushed my teeth first, waited 30 mins, and applied the trays (left on for a max of 20 mins). My teeth were too sensitive to do these daily so I did space them every other day.

I haven't used the product yet (and yes, I hate it when people do this), but wanted to give everyone a heads up that it needs to be refrigerated. After a week of it sitting on my counter, I finally opened the box and read the directions, and buried at the bottom was a little note that these trays need to be stored in the fridge. This not written on the outside of the box or anywhere else on the packaging. This is no indication that the were refrigerated in the warehouse, either.Also, the timing on the instructions appears to have been written wrong. It says: 10%, 30-60 min. 15%, 15-20 min.

I liked this teeth whitener, but honestly I was expecting something that would make my teeth whiter… I wouldn’t recommend buying it with this dosage
