I absolutely love SNOW, I used to use the Crest whitening strips for years. I got a present last Christmas of the SNOW set and haven’t looked back. The only problem I have with SNOW is the length of time for delivery, I ordered a set for my mum for this Christmas and it still hasn't arrived, I had nothing to give her on Christmas morning which was completely embarrassing!!! I also have received no emails about delivery dates etc so I’m very disappointed! So I still have no idea when it will arrive!!!! I may have to look into another product for the future as I ordered well in advance and still no delivery!! As a result of this I shall be very reluctant to order again.
