These things work. That’s all I have to say! No issues whatsoever. Maybe a TINY bit of sensitivity...but I have that anyway. I noticed a difference in like...a week maybe? Would definitely use these again.

I think they did their job but I’m a triple threat to white teeth - I drink very dark black coffee, eat dark chocolate and drink the darkest of red wines. I think if I ate less staining food I’d see much better results.

Really does whiten your teeth! I love these whitening strips because of how well it whitens. Be careful however, using these too much can damage your enamel and make your teeth very sensitive to hot and cold.

Truly love these! They are kinda pricey but super worth it. I usually use them every two months and if I forget then I will use them two to 3 times in one mouth to get back to my white and then just once every two months! Definitely recommend!

Stunning! I bought 2 boxes and my teeth are so much whiter! The strips took off years of staining from coffee and tea and all other staining foods! So amazing, and I reccomend to all my family and friends and may even buy my sister a box!

I use these products every couple of years to make sure my teeth are looking good. I’m in avid coffee drinker so I feel like my teeth tend to be on the more yellow side. Using this product helps me keep a white smile. Will repurchase again.

This product works fast and gives great results all the time. I love this product and I'm in love with white teeth. This will be a prefect Christmas gifts for others. It's affordable and safe. Just follow the instructions.

I’ve been using these for as long as I can remember! I don’t use them as much because I’ve reached an amazing level of whiteness since I’ve started! I will ALWAYS be a repeat buyer for these. I’m an avid coffee drinker and still have pearly whites!

I used the 30 day kit approximately 15 years ago and to this day people ask me how I get my teeth so white. They’ve been glowing since although I will probably be buying this kit again within the year to reboot that glow. It reallllllyy works.

This is an amazing product. It works SO well and makes my teeth very white. I would be careful if you have sensitive teeth, however, because it can hurt a little bit. Overall love this product and would suggest trying it
