I think this product is very practical because you don’t need the trays. It took a while but I got my teeth white by the end. I didn’t have problem while using it and the price is not that expensive.

Literally the best of the best! If you want whiter teeth ASAP this is your product. I will buy these again and again because they are just that good!! You need these in your life

This product did absolutely nothing for me, I used the entire box and was left with no different result, quite disappointed. Satisfaction not guaranteed, and still no refund. I would never waste money on these products again.

[This review was collected as part of a promotion.] I love it. It's easy to use. The taste is pleasant, the packaging is practical, and the price is good. I see results in a week. My teeth are whiter; it's real and effective.

This is the best whitening strips I have ever used. In just 2 weeks after 2 uses, my teeth are visibly whiter. The strips sit on great however large amounts of saliva can loosen them, so be aware. Other than that they are wonderful!

I love using these! I get compliments daily about how white my teeth are from using them. I notice a difference after just one use. Crest 3D White Luxe Professional Effects Whitestrips - Teeth Whitening Kit

Good product, but I just can’t bring myself to use them as often as suggested. I may use them 2-3days in a row every few months or so as a whitening boost.

I’ve been using crest strips for years & I can’t recommend them enough! They work great, only downside is your teeth might become sensitive after a few days of using strips.

These work pretty well for a store bought whitening system. I use these when I need a boost in between my gel from the dentist. Go for the sensitive option if you have sensitive teeth!

These are inexpensive and highly effective! I use them once every few months to maintain whiteness. Be careful if you have sensitive teeth not to wear longer than the recommended time.
