I used these for 4 months along with brushing my teeth and then it started peeled my enamel off like it was nothing :( I'm not impressed one bit I would never recommend this to anyone also got rude comments when I called the complaint in..

These work so well to whiten your teeth. So if you need to whiten your teeth for a wedding or a special event these are perfect to use. They are easy and they work really good! They whiten your teeth instantly and you won't be able to stop smiling after.

I really like this whitening kit. I've used it for many years and found it to work wonders. It removes stains and leaves my teeth looking great. The only problem I have with it is sensitivity after using it. My dental hygienist suggested that I use a sensitive toothpaste before and during whitening treatments and it helped a bit.

Very expensive, but whitens well. It does really increase my tooth sensitivity though

I tried this and it is not the best for me, I don't like things in my mouth and definitely not for longer than a couple of minutes. I am sure some people can handle it, but it is not for me

I buy this product for my 18 year old daughter who absolutely loves this product and wouldn't do without it.

I'm looking for a quick fix for whiter teeth without having to go to a dentist. I will be giving this product a try.

I was disappointed with these 2 hour 7 day strips I didn't notice an amazing result with them. I got more compliments on the 30 day level 3 strips than I did with these... I bought them when I was finished with Invisalign and it just wasn't as awesome as I hoped.

I did not have sensitivity issues while wearing them, I noticed my teeth were a wee bit sensitive the next day. My boyfriend tried them and said they immediately hurt his teeth after 5 minutes.

While I have had success with the other strips, perhaps this one just didn't work well with my teeth? Next time I will just purchase the 30 day kit instead.

I would recommend this kit to someone looking to whiten their teeth fast, I just didn't get the results I was hoping to get from "intensive professional" whitening strips.

This product left white spots on my teeth and made my teeth super sensitive and very painful. Not a very good experience at all.

I used these after getting my braces taken off to quickly whiten my teeth and was very pleased with the results. They were slightly uncomfortable to have on for so long but it was definitely worth it to get the results after!
My teeth were quite noticeably whiter and the effects did not wear off. For the next couple of days my teeth were slightly sensitive but nothing too drastic. Would definitely recommend this product!
