Difficult to use, doesn't appear to work.
I purchased this item based on previous reviews, but am extremely disappointed.  I received two very tiny tubes of the product which appear to be relatively dried out.  There are almost no directions regarding shaping the trays, and if I hadn't done this before with sports trays for my kids, I would have no idea what to do.  I then had to squeeze the tube hard to get any product out.  I placed a drop of product in the tray as directed and spread it around.  After three nights of usage, there doesn't apear to be much difference in the color of my teeth.  They're pretty white to begin with, and I just had a cleaning, but they don't appear to be any different at all. I won't buy the product again.  I wonder if I received a different type of kit that what the other people commented on.
