Review title: Stick to Crest Whitestrips
Product review: These Aquafresh trays are a waste of money. They are very uncomfortable and hard to keep on your teeth and the gel does not spread through the tray...you still have clumps of unused gel in the tray after your 45 minutes are up. I personally like the crest whitestrips 100% better. I only tried these because they are new but would never buy them again.
