I give this product 5 stars, because it really does whiten teeth! It works better than any other whitening product I've used. I have sensitive teeth and these strips do hurt some but if you only use them once a day (before going to bed), then the sensitivity is gone by morning. Since I only use them once a day instead of twice as recommended, it takes a little longer to see the results but still works just as well. I loooove my bright white teeth now! This product works great, is worth the price, and I would recommend it to anyone!!!

This was so great; I could not ask for a better result. I used the whole packet, and my friends said wow! They all went out and got them. Now I smile at everything just to show off my teeth. :-)

After being told that Whitestrips were the way to go, I decided to give them a shot. Now, I'm driving my fiancee nuts bragging about how white my teeth are after only 7 weeks of the regular strips twice a day. They do hurt your teeth and wear away at your gums. The other downside is that the strips really aren't long enough to cover your entire smile. They make it to your incisors, but not past to the molars. I have a small mouth but even so you can see a few of my molars when I smile. I still want perfectly white teeth, which looks like it's going to be unattainable without professional whitening. Still, the money I paid for this was well worth it.

Too bad I can't give it lower than a 1. First of all, these things taste horrible. Second, they slip off after about 5 minutes because of moisture in the mouth and saliva. Second, my teeth started aching. I ended up only using about half of the strips with little results. It doesn't work well on crooked teeth either.

I really am impressed on how white my teeth are already after only 5 days of application but I am finding my teeth are sensitive now. But, I would recommend it to anyone who wants a brighter whiter smile!!

Great! I smoke and this works really well. My teeth stay white for a while. I usually throw it on for a few days and then skip a couple of weeks. But it definitely works!

I haven't noticed a drastic difference, but my teeth are a little brighter. I have sensitive teeth, so I was nervous about using them. However, I have not had any problems. I use toothpaste for sensitive teeth, so perhaps that helps. My teeth are not perfectly straight, but I was able to manipulate the strips to cover my teeth without any problems.

If you ever had braces or discoloration due to other factors, don't bother with this one. It didn't work for me. Also, it makes your teeth sensitive for a loooooooong time. Not recommended.

This has given me my smile back! They really work. My teeth were never really white. I am 27 and I have wanted to bleach them since I was like 10. But this product does what it says! My family has noticed my teeth. Even my sister and boyfriend want to use them. Crest Whitestrips- 30 bucks. Being able to smile again- Priceless!

After trying a bunch of whitening toothpastes and having none of them work, I finally decided to cough up the cash for these whitestrips. The first week of using them they made my teeth a bit whiter (I wasn't able to use all of them during the first two weeks because applying these twice a day hurt my gums, so I stuck with once a day). I must've spent an entire month to finish the box. During the second, third, and fourth week, my teeth did not get any brighter or whiter than they did the first week. I figured this product didn't work; however, my teeth progressively got whiter (with regular brushing and flossing) every day for an entire week after having stopped using the whitestrips. It was strange, but these do work. Yes, they hurt my gums somewhat at times, but they made my teeth a lot whiter and that's what counts because that's the only reason why I chose to purchase this.
