These are so easy to apply and stay put on your teeth for the duration of whitening. They don't slip as much as other brands. They smell pleasant and taste ok as well. Most importantly, they made a very visible difference to my teeth after a few treatments. I could really notice how much more white my teeth were and I get many compliments, whereas I got none before. This is all the proof I need that these are worth every penny.

These are probably very good for a lot of people, but not for me. They actually hurt my teeth. I followed directions but my teeth seemed to be overly sensitive to them. I don't know why because my teeth are pretty healthy.

I tried these 3D Whitestrips and was completely impressed with them! After just one use I noticed a difference, and after 4.....wow my teeth are so white they look amazing! I did notice a little sensitivity after using them for an hour or two but then they were fine. I also like how they sat in place very well for the two hours. They work so well I just use them now once or twice every couple weeks! Yes they are costly but no where's near as expensive as a trip to the dentist for the same results!

Je trouve que les Whitestrips fonctionnaient mieux avant. Je ne sais pas s'il y a eu un changement de formule, mais je n'ai vu aucune difference lors du traitement. Je l'ai séparé en 2x plutôt que 14 jours consécutifs car ça fait super mal aux dents pour 2 jours, l'email en prend un coup ! Je n'en racheterais plus.

These whitening strips are some of the more expensive ones out there but they are worth it because they work! These are super easy to apply, don't slip off your teeth as you're waiting for them to do their thing and they definitely DO whiten the teeth by a few shades. I did find they had a bit of an odd taste to them but they are very effective. I would use them again.

I like using these because they work, the have definitely whitened my teeth and if you don't use the strips everyday they last quite awhile. The only downfall of them is the price, they are relatively expensive.. But you pay for quality right.. I will buy them again for sure because they do work.

The effectiveness of these strips is spot on, since they did manage to whiten my teeth and make them a few shades brighter, but I did have to discontinue my use of these strips after about three uses consecutively. If you naturally already have sensitive teeth (issues to cold or hot foods/beverages), avoid these strips at all costs! They just prolong the issue and make it worse.

This is pretty pricey but I was able to buy it twice and I love it,it does whiten your teeth,I wasn't a fan of the taste of the whitening gel is kind of gross, but I was pleased with my overall results ,I just wish it wasn't temporary ,it only lasted maybe two months

I find that this product does exactly what it says. It whitens your teeth, you can see results after just one use. The only problem is that I already have very sensitive teeth so it did not respond well to me personally. I have heard nothing but good things from others, though

I love this product and use it once a year to keep my smile pearly white ! You can see the difference pretty much immediately, which is a must if you're a coffee or wine drinker . The only teeny tiny downfall for me was that my teeth felt pretty sensitive for a day or two afterwards. It does go away though . It's a bit expensive but I find I only need to use it about once a year. Would definetly recommend this to a friend!
