Forgive me if I've stuck this in the wrong place...
Due to the pain, tingles and numbness that has very recently manifested - itself I've invested in one.
On my first go I wound it up to the mid 40's and it felt great.
Extremely relaxing ...except when the thing decides to really give you a pummelling.... which is what I had mine doing.
I did note that my left foot is far more sensitive than my right, at the lower values.
I'm putting that down to using less moisturising fluid on the right.
I'm now finding that the toes on the left foot are aching like mad BUT a nice ache like they've just had a full on work out.
Let's see how things progress...or more likely don't.
