Review title: Trays slip off easily
Product review: I have used most of the box, and the trays slip off my teeth very easily. Once I get them in place I cannot release the pressure on my teeth at all or they slip, some of the gel comes out into my mouth, and they are not as effective. Also, I have receding gums and these trays do not even come close to covering all of the length of my teeth. They are also VERY short—they only cover the front teeth and do not reach very far around to the sides.Despite all that, my teeth do appear to be whiter, but they are unpleasant to use. I just ordered another product, SuperSmile, and I'll see how that goes. it's not a tray, so it should solve several of the problems these trays have.
