Only way I whiten my teeth. Mild enough that they don't make my teeth sensitive and work fantastic! Better than any other brands I have tried in the past

It all matters on how sensitive your teeth are. Mine aren't too sensitive so this works wonders. Makes your teeth into pearly whites in minutes. You can also get the off brand ones if these are too expensive for you, they literally work the same.

I highly recommend this tooth whitening kit. You only need to use it once or twice a week. Put it on. Leave it for 15-30 minutes. Take them off. Brush your teeth and you will see quick results! I recommend to everyone!

I love how well these work on my teeth! It makes my teeth so white after a few uses! He only downside is my teeth feel extremely sensitive sometimes after I use them. I heard using sensodyne with them helps reduce that though! I'll have to try it.

I use the Professional Effects strips about once a week for maintenance. My dentist complimented my white teeth and told me to keep doing what I was doing. These work!

These work very well. I don't use often, because they do cause some sensitivity, but after using, my teeth look amazing. I have tried other brands but these seem to have the best effect. Will definitely repurchase.

In only one use, I truly felt that my teeth were way whiter than they had started out being. The effect does wear off however, so it's not meant to be only one use. Overall, satisfied!

Whitenings your teeth but makes them extremely sensitive. Loved the effect but cried when I had them on for like 4 minutes. So much pain cake from this product. Would rather bleach my teeth than use t hi s

This product did make my teeth appear whiter however it made them very sensitive! Even just talking was hurting my teeth. I have tried the sensitive brand of this and it had the same effect on me. I would not buy again.

I would give this the five stars if I had something to compare it to but I don't! They worked really well and I can see a good difference in my teeth! I've used this product multiple times and will continue to do so!
