These work if you need 1-2 shades lighter but it's nothing drastic. If you're just wanting a pick me up between dental trips, they work. I still recommend seeing a professional though.

The whitening effects of these strips are great. I did find my teeth got a little sensitive with this which I would expect with any white strips. I use them every so often to maintain whiteness

I do NOT like these. I've tried these again on and off for years in hopes that it would work for me, and it doesn't. It leaves my teeth super sensitive, definitely not worth the money for me. 

Only after using the second strip, I got white stains on parts of my teeth like those caused by floresis. I am extremely depressed and disappointed. My slightly yellow teeth were much better looking.

I really like the results this product gives and they grip to the teeth well so I don't have to worry about sliding. The one con is they make my teeth sensitive, even after following recommended wear time. But still a great product!

These don't stay on my teeth very well. It does a good job at whitening but always leaves part of my teeth not as white since they slide around during the application.

Started using it before a big event, even though I really didn't Believe it will do any thing. Omg this product changed my life. I got so many complements!. Never felt had that much confident smiling :).

I actually saw a difference in using these. My teeth are fairly stained from being a heavy coffee drinker, and these strips really helped remove those stubborn stains. Overall, I'm truly satisfied and I will be purchasing regularly.

I will never use anything else to whiten my teeth. The results are instant and provide a great overall whitening of my teeth that lasts and continues to withstand staining. Although slightly more pricey, they are completely worth it.

I've been searching for the right kind that actually works! I finally found it! You can actually tell a different after the first use! I use it a couple of times a month! Totally recommend
