I think this may have damaged my teeth.. I would not purchase. Read more

First time ever using one , so I don't have anything to compare it to. But I'm satisfied with the results I saw while using this product. I only used it a few or more times over a two week period and that was enough for noticeably whiter teeth. It's easy to use. I didn't find it as uncomfortable as I thought it might be. It had a nice feel while placed in my mouth and wasn't too bulky. The charge lasted me multiple uses in a row before having to recharge Read more

It is not whitening my teeth as well as the strips. Read more

Okay, here's a brief review. The whitening kit comes in a very nice box with the mouthpiece, light, and three syringes containing the whitening gel. The instructions are on a hard card stock and are very simple and easy to follow. A graded chart is included to judge how white your teeth are becoming. The light is easy to use. Just push the button. It shuts off automatically after 10 minutes. The mouthpiece is comfortable, but too small. It won't reach your back teeth. Plus, it's not deep enough for the gel to cover the entire surface of your teeth. Half of your teeth will be whiter...the other half...the same. The gel has a bit of a sour flavor. It also will sting your gums a bit. Here's how it works: Put the gel on the mouthpiece -- top and bottom. Place in your mouth and push the button to light it up. Hang out 10 minutes. Rinse when done. You will see a difference. Your teeth will be whiter...but not professional-cleaning white. I tried something different. Instead of putting the gel on the mouthpiece, I put it on a toothbrush and covered all of my teeth. Then, I put in the mouthpiece and pressed the light. It seemed to work better. If you're not looking for professionally-cleaned and whitened teeth...this is a good little unit to brighten your teeth a bit. If you need more...go to the dentist. Read more
