So far so good.., I've been using this product for about a year. A new cat for my car is about $1800.00 so for about $40.00 ( 2 bottles) this is a great alternative. The first time One bottle in a 1/4 tank of gas was enough for about 2500 miles. The next time , however, it lasted only about 200 miles. I then used 2 bottles in a 1/2 tank of gas and it lasted about 4000 miles.

Great song selection. You really will be moving with this. just dance has really improved since the first game!

It works. It's pocket-sized. The color-codes are printed on both sides of the device. It was reasonably priced. Recommend.

This is amazing if you have a bump on your car and rub it with this most of the time the black comes off wonderful.

I've been using Crest Whitestrips for years, ever since the original product was released. Crest continues to refine the product, as it becomes more powerful, requires less time, and with better adhesion. I'm at a point now where I just use them for a few days every couple of months for upkeep. Their effect is noticeable, both to me and to friends who comment on how my teeth look whiter. Without regular maintenance, my teeth would be fairly yellow and dull-looking. No, Crest does not give me the blinding, "Hollywood-type" white, but that's not what I want, anyway. Instead, they look bright, natural, and definitely more white than yellow.
