"Easy to use and cordless"
I have been using this product for three weeks (one hour a day) and it seems to have improved the osteo-arthrosis in my knee and also the numbness, in my affected toes, has all but disappeared.
It is not at all uncomfortable in operation (even at higher output levels) .
Time will tell if the improvements continue, but, so far I am impressed with what it has achieved.
Not a cheap purchase, but a well made item. Money well spent.
