They stick on your teeth well compared to other brands. My teeth were so much whiter after completing all the strips. The only downside is I had mild sensitivity.

It does improve the whiteness to your teeth but it won't happen quick this one takes a while for it to build up and it also gives you a weird sticky feeling attach to your teeth and the taste is awful

These are ok. Makes my teeth really sensitive after using. The taste is awful. If you can push through the taste and jelly feeling on your teeth, you'll be ok with product!

Really like.this.product ... dentist recommend this to me ..so I tried it ...so happy I did ...even so ...my husband tried them...great results ...Easy to use ...

These white strips are amazing. I noticed a huge difference after just 2 days! It hurts a little for my sensitive teeth but I really didn't mind because of the immediate results. I loved the outcome and I would recommend to anyone.

I love the whitening strips. I have been using them for years to brighten my smile because I love my coffee but my teeth get stained. This product works great.

The crest stripes are a little on the pricey side , but they have made such a huge difference in my teeth and make them probably 2 shades whiter ! I use these maybe twice a month and I am obsessed. I drink coffee and my teeth are still super white!

I really like these but they kind of hurt my teeth. Also they kind of taste bad. However they do make a difference in terms of whitening and they are pretty inexpensive. There are often coupons for them online.

Holy cow, do these hurt my teeth! I've been trying to whiten my teeth for a while now and tried these out. They're pretty pricey but much cheaper than professional whitening. They brighten them a little but at the cost of super sensitive teeth!

These work and are actually better for your teeth than whitening toothpaste. This does as promised and shows results within 3-4 days. I liked it but do not use too frequently as it causes tooth sensitivity.
