Great whitener, easy use & reasonable price!
I think the product is good for whitening. I've been using it for about 1 week. I drink coffee and was noticing some browning. They already look whiter and I've only been using it once daily. It also seems to be doing a good job on the two front upper teeth which are veneers. All in all, it easy to use, does the job of whitening and is reasonably priced. Don't think you can beat that!
