Is good 2 1

I bought this in part because I had painful tension in the back and unfortunately very quickly get back - so that a massage each gives me only for a few days relief.
With this device, I can have a good part of which now do it yourself - although it can not completely replace the hands of a specialist.

Plus points:
+ Pleasant hard (no additional pressure necessary to apply)
+ Long handle (can be used on their own backs)
+ Long cable (~ 3m - ranging from bed or the couch to the next outlet)
+ Strong vibration (good for muscle relaxation to the depths - but by the not lovemaking, or hard to use;))
+ Quiet (I was expecting a lot more noise)
(Depending on the type and position of bracing the massage heads can be very easily and quickly replaced) + several papers
+ Acts robust (if it is also to be seen)

Bad points:
- Infrared heat is not felt (as I would have expected) - therefore 1 star deduction

Neutral:
> Big - therefore suitable for self-massage - need in the closet but plenty of space
> Power dependent - no tiresome battery change - it does not need a power outlet to be too far from the bed / couch

All in all I am satisfied with the device and can recommend buying.
