Whitenings your teeth but makes them extremely sensitive. Loved the effect but cried when I had them on for like 4 minutes. So much pain cake from this product. Would rather bleach my teeth than use t hi s

Literally love this product and the way it makes my teeth look. It allows me to feel comfortable when I'm ready to go out because I know my smile will be bright.

Holy grail!!! If you wanted to whiten your teeth quick, effective, and cheap this is the product for you! After just three uses I noticed a huge change in the shade of my teeth. I would recommend this to others

I've used these whitening strips a few times. They're fast acting and work pretty well. They left my teeth a shade white after using every day for 2 weeks. I only wish it worked faster and wasn't so pricey.

A cult favorite for years, these white strips really do work! Unfortunately I have super sensitive teeth so I can't keep them on as long as needed but they definitely work.

Amazing. It takes a while for it to work, I would hope this worked a little faster, but over all, this product is great. If you are sensitive to taste I would most likely avoid. It does the job, but with time.

I love this product! I use the strips about twice a month to maintain a sparkling white smile. Though other products can create tooth sensitivity, I find the crest brand creates minimal sensitivity with maximum whitening!

I did enjoy using this product. It did help whiten my teeth. The only thing I did not like about this product was that it was very hard to keep it placed on my teeth the right way. I do not think this product is worth what you pay for it.

These made my teeth very sensitive. They do whiten but I had sensitive teeth for a week. I would not use them again. But if you'r teeth don't get sensitive they are great. 

Used these for a few days and they worked well, could have worked a little better in my opinion but still worth the purchase if you're looking for an affordable option.
