Title: Rather use strips
Review: I had been using the white strips and decided to try the aquafresh white trays.They DO whiten your teeth, but the bottom tray will NEVER stay on, ever. Top tray is good and reliable and works if you only want half of a white smile. Again, the bottom tray wouldn't stay on and didn't cover my teeth completely.Hope this helps!
