A great product

I ordered this item online and it was delivered very quickly. After the very first use I could see a difference. Only a tiny amount is needed and I followed the guidelines for 15 minutes.....it really does work.
I will certainly order this again but it could be some time before I need to as a little goes a long way. I have used it now for 7 days and have not had any sensitivity issues. All in all, an excellent product and excellent service.
