I absolutely love this product it's amazing it does great it doesn't have the best taste in the world so that's definitely something I feel like they should improve! I recommend this to all my friends! 

It was okay, it whitened my gums which was obviously a weird look- it made them actually white, but they did whiten my teeth a little bit which was awesome I just wish it was more permanent. Not sure if I would buy it again

These are okay I guess. It probably works for some people but it did not work even the slight for me. It also tasted horrible and I couldn't get the taste out for a long time. I'd recommend people giving it a try but I wouldn't use it again.

I have saved so much money with this at home strips they really do whiten. I would only use them as recommended and would not leave them on for any longer than that because they will cause sensitivity like any whitening product.

This product is very effective. But be careful... don't overuse! I made that mistake and my teeth became overly sensitive and my gums were very irritated. My teeth become noticeably whiter once completed.

I liked it, it was a little strong on my gums, but got the job done. I am a Dental Hygienist, and I prefer the crest to in office whitening. I think it's gentler and just as effective

My teeth are naturally yellow and this product make them lift from yellow and make them white however it is damaging to my enamel a lot and made my teeth very sensitive so I would use with a lot of precaution.

These are very easy to use at home. For teeth well and are not uncomfortable. However, they do still tend to make my gums/teeth sensitive after some use.

I like these but they give me a lot of sensitivity which I don't like. I follow up with Sensodyne which seems to help enough but I wish they would put some helpful ingredients in there so I didn't have to use a whole other product.

I love crest white strips I've been using them for years the only thing is it isn't good for your enamel I've noticed some changes in my teeth throughout the years from it but it does get your teeth extra white overall
