Definitely a treat, with minor shortcomings

Because of the frequently occurring cramped back muscles in the upper part we have gained us this little massage wonder where I was admittedly skeptical at first. Meanwhile, I do not want to miss this little device, however.

+ Good massage effect. For me, the two directions of rotation are sufficient also completely.
+ Small and compact, can thus stow away.

Neutral I rate other hand,
+ - ... The volume of the engine. As "soft", as specified in the product description, I would not describe this now, but the volume is very limited, to say: It is fair to watch TV undisturbed.
+ - ... From the heat I see absolutely nothing. Here I would have any additional controllers required for different heat levels.
+ - ... The two rotating balls are quite hard, which is why I always put the massager into something soft, yielding, for example, thick, firm pillows. Thus, it is then for soothing massage experience at least for me.
+ - ... The auto shut-off after 15 minutes bugging me pretty. Again, I would have liked an option.

Conclusion: A real massage so does not replace a device, of course, let alone that solves specific tensions. Nevertheless, the unit was worth the money for me.

All in all, I forgive 4 stars. :-)
