Maybe you have to use it consistently to see results because i didn't find it to be too helpful. But it has easy application and there isn't much of a taste or anything either.

They work really well and it's nice because I definitely don't feel like they're ruining my teeth or burning my gums like other whiteners do. Unfortunately, it is only a temporary fix and will not keep your teeth white.

I found these work best with crest 3D toothpaste. It helped brighten my teeth in a weeks time. I never Jada problem with sensitivity while using these. You can find plenty of coupons to use on these.

Super easy to use, and I love that it takes away the coffee stains and leaves me with a bright white smile. I'm an everyday person and am trying to achieve celeb worthy white teeth and this is slowly getting me there!

Literally the best and easiest way to make my smile sparkle. It doesn't hurt and it's so easy to use (I've had no issues at all). I get asked a lot when I use it what Doctor I use for teeth whitening

These 3D white strips had my teeth shining in no time. I was so skeptical but they proved me wrong. It does taste a little weird but that's what they all taste like. I was overall satisfied and will be buying again.

I have saved so much money with this at home strips they really do whiten. I would only use them as recommended and would not leave them on for any longer than that because they will cause sensitivity like any whitening product.

I used these whitestrips as a test to see if they really worked and they do. This product is very effective in getting your teeth to the next white level. I used this product every night after I brushed my teeth for the best results 

Crest whitening strips are gold!! I use once a year and my teeth stay very white. I drink tons of coffee so it's a great products. I have been getting compliments on my smile for years and I owe it to these!

These are one of the first white strips i've noticed a huge difference with! They aren't the best for sensitive teeth so maybe don't leave them on as long if that's a problem for you!
