I noticed a difference in my teeth after the first set of strips, but I was not very convinced, so I did a second set of strips the next day and there is no doubt these strips work!! I think two sets got my teeth at least 5 shades lighter. I am not sure if is safe to used them every day like I did, but I thought I was necessary because my teeth were very yellowish.I feel a little discomfort and sensitivity on my teeth but I not planning to use another set soon, so I think the sensitivity which by the way is not too bad will go away within a couple of days. I just hope the results last long enough so I don't have to apply another set of strips in the next month or so. I do recommend this product.

Started using these as soon as I received them. I love that they are a single strip and do not have to fold over the teeth. After my first use I noticed my teeth already getting whiter. I was also able to speak while they were in my mouth, which is not always the case with whitening strips. This pack also comes with two bonus strips that are supposed to be left on for an hour, which was nice to try!

I’ve tried a few whitening products before, but these strips really impressed me. Super easy to apply they stick well and don’t slide around like others I’ve used. I started seeing results in just a few days, and after two weeks, my teeth were noticeably brighter!

These are easy to use and stay on better than older versions.

These 3D whitening strips really deliver noticeable results. After just a few uses, my teeth look visibly whiter and brighter. The strips fit comfortably on my teeth and stay in place without slipping.

Great value overall. My teeth are noticeable whiter and my face is much brighter. I used these as directed, daily. I did a 1 hour express before the classic 10 and finished with a 1 hour express. I have sensitive teeth and only a couple of nights noticed some mild sensitivity before bed. I used a sensitive toothpaste during treatment.For reference: i drink 1 cup of coffee per day, I do not smoke, i do not drink red wine

These definitely made my teeth look whiter after a few uses, but they really irritated my gums. After the second day, my gums felt raw and sore where the strips touched. The whitening works, but if you have sensitive gums, I’d recommend being careful or trying the sensitive version instead.

I’ve always been skeptical of whitening strips. My coworker uses crest strips and his BRIGHT white teeth. So I gave it a try and I’m only 4 strips in and it’s noticeably whiter. Teeth haven’t felt super sensitive either
