This was bought as a birthday present for me and I find that if you mfill it with colled boiled water it isnt as sensitive on your teeth as with cold water, it is a bit of a shock when you first begin to use it but my mouth feels clean after using it
I brought, in short time it stop working seems product quality is bad
No, I would not recommend this to a friend.
