They really do work! I used to be a heavy smoker, and had nicotine stains on my front teeth. I used these twice, and they got the stains off my teeth. They also didnt leave my teeth sensitive at all.

These white strips really do work, but they make my teeth extremely sensitive. I can usually only wear them once or twice a week and they typically recommend wearing them every day. I wish they would come out with a version for sensitive teeth!

These work so good it’s not funny! Every now and then I will put one in just to stay on top of it and I love it. However, if you have sensitive teeth this is not for you unless you space out your whitening sessions.

My teeth were immediately a few shades whiter and brighter. They are definitely effective and I don’t have any critiques for this product because it 100% met my expectations. I would buy them again in the future.

I have noticed a difference in my teeth when I’ve used these in the past. I’d say the effect lasts about 6 months. They can be a little pricey, and product form my dentist works better.

Love this product! It is so simple to put them on and lay back and watch a Netflix show. set your timer then take them off, it’s as simple as that. They really whiten your teeth if you stick to it. I would recommend to everyone!

3D whitestrips are always good to have on hand for a quick whitening. Repeat customer right here!!! I used to have deep stains from coffee, but these strips removed it!

The best way to whiten at home if you ask me. Fast, efficient and economical. It’s the best of all worlds for someone wanting white teeth fast and without seeking a professional - would highly recommend to a friend

I was a little hesitant to buy these because they cost a decent amount and seem out of my price range on some days, but I gotta say they are completely worth it!! My teeth looked and (surprisingly) felt great!

This was very effective at whitening my teeth. It’s a good product for getting it done in a short amount of time. Using it caused a little minor pain, but no long term negative effects.
