I've been using this for about a month, and I was totally surprised to find that it really does work! I've tried other teeth whiteners, and this one worked better for than the rest. Instead of using trays or strips, you simple squeeze a little out on top of your toothbrush with your toothpaste and brush as you do normally. You can use it everyday (up to three times daily), and it takes no longer than brushing your teeth. The taste wasn't too bad, but it does have that distinct whitening gel taste. Usually whitening systems make my teeth a little sensitive, but I haven't noticed any problems with this. The only problem I had was getting it out of the bottle. You're supposed to store it on its cap and tap it before using to ensure a good flow. The first few times I had a hard time getting it out of the bottle, and it squeezed out way too much when it did come out. Overall, it's a quality product, and you can't beat the price!

I bought this about 3 weeks ago and it WORKS! Its very afordable alot cheaper than those strips. And in my opinion works better. Plus theres no yucky taste! =) You just put your fav. toothpaste on and the booster on top of your toothpaste. Then brush like normal. You can use this product up to 3x's a day. And it lasts a long time!
