Aquafresh white trays

I have tried several type of whiting strips for my teeth.I do not smoke but I am a coffee and diet coke drinker, so my teeth sometimes look not so white.I have tried the whiting strips....what a mess. Don't stay in places, leave a thick gel in your month and on the teeth.It seemed to work but I did not like the mess.So, I tried Aquafresh White Trays what a refreshing change.No mess, just open the packages put the trays on the upper or lower teeth and it does stay there with no mess and no thick gel stuff let in your month.This works-- whitens your teeth and I think it it so much easier and less messy.I would recomment it ... give it a try and see the difference in the trays vs. the strips.The cost is about the same and I think you do get your monies worth.A good value.
