It’s really helpful in a short time I had an amazing and bright smile. I would recommend to everyone

Great for when you need a quick whiten fix! We buy these when we have an event coming up or family pictures.

Definitely saw at least 3 shades difference! First time I've had that happen with any whitening product!

Love these whitening strips! They actually work and they are great for sensitivity, I never had any problems with this brand!

I decided to buy some Crest Whitestrips after not using any for 3-4 years. The results of the Professional Effects strips were amazing!!!

I wish there was a sensitive teeth formula that still had the whitening strength. The cost is reasonable.

I use these white strips about once a month in order to brighten my smile. They a flexible and conform to the shape of my teeth pretty well.

These crest whitening strips aren’t effective. I didn’t see a difference when I was using these strips

I found this product to be very easy to use. After using this product I had very positive results. A good product and also very reasonably priced.

I’ve used it and it was great for me. It’s a complete kit. And it for sure makes your teeth more white
