I bought it for my son and it was recommended by a super comfortable doctor and it's exactly as they describe it

The product is the same as the post I don't use it yet

I liked it although it is not to use it for a long time because it is for a certain time, you rest and use it again, the vibration despairs if you have it in function because it vibrates for everything, so I turn it off.
