I've tried different stuff to whiting my teeth nothing works I did try this out still didn't work I didn't see any results from these 

I love this product so much! It is expensive in my opinion, but worth the price for what you get out of it!

I would highly recommend this product. The quality is great. It's affordable. I personally will be buying this again!

I use these whenever i have an event and it is a great way to whiten your teeth. it met my expectations and was very effective

These left my teeth feeling quite sensitive after, for about 3 days. However, the sensitive type of the crest white strips were amazing!

I wish these weren't as expensive as they are, but when I do breakdown and spend the money I am left with the whitest teeth ever!!

When first using these, I've waiting a few days for the product to work and luckily, it did ! My teeth look much whiter.

I dont think this product works as well as others on the market. The strips come off really easy and slide around in your mouth. 

Amazing. This work very effectively. The one bad thing about these is they do not cater to sensitive teeth.

These work - but proceed with caution. My teeth became pretty sensitive after using. Immediate results are apparent but it's pretty subtle.
