I've never whitened my teeth before because I worry about damaging side effects. The charcoal is a safe solution and it works. The powder was a strange sensation at first. Despite being messy it is easy to use. I wouldn't use this first thing in the morning because I did have some black residue around my gums for several hours despite thoroughly brushing and flossing. Nevertheless I'm very satisfied with the results.

This stuff took 3 months to make a real difference, but the whitening works better than bleach or laser -- and it lasts. Will buy again.

I love that in just one use I noticed a big difference with it whitening my teeth I would differently purchase again.

Such a great product. You can definitely notice the differences in a matter of days! It can be on the messy side though, so I suggest to use the powder while showering.

Seems to work--have only used it twice.

The packaging for this product is super cool. I love how professional it is. I would rather much do this than go to the dentist for teeth whitening, as I'm so afraid of the dentist.

Great tooth brush sturdy, medium soft, love it!!!

Softer than expected.

This is an incredible product. In only a week my teeth have gone several shades whiter than they were not even doing it every day. It is extremely easy to use and quick! You can't beat the price. I can't wait to try other SmileTime's products. Very happy with this purchase.

My wedding is next year and I want my teeth as white as my dress! I will tell all my friends to buy this kit!

Unlike another brand I purchased and returned, this was a substantial light and tray and came in a protective box. Teeth slightly whiter after one use!

This is one the best home whitening kits I’ve ever used, and for this price you really can’t go wrong. I recommend it 100%!

I like the product I've used it for 2 days now and I see some change.

Nice kit, easy to use, everything came in the box simple to figure out. Have used once and feel it’s already lightened the coffee stains from over the years a bit.

The price was affordable for the effectiveness. :D
