Positive noticed:

+ 3 light and comfortable settings with adjustable heat, warming up the machine each quickly
+ Quick Start Guide in paper form
+ Easy handling
+ Oeko-Tex Standard 100 certified, contaminant-free product

Neutral:
0 cable length is not too short, but beautiful would be a somewhat longer cable
0 is heated only the top of the unit above the instep, although you feel the heat, but I do not feel the heat distribution than optimal, which would likely be the case for example, when the heat would be carried out on all sides, even from the bottom

Conclusion:
The device is really suitable for warming the feet and it is also a convenient device. Although the heat distribution is not quite optimal in my opinion, I give even 4 stars.
