The massage and heat function is very pleasant and relaxing. The device is relatively large and heavy, and therefore takes quite a bit square. Under the desk but that does not matter, when switched off, it is used even as a foot rest. The build quality makes a high quality impression. Only the plastic balls for the actual massage look a bit cheap.
Negative is the volume in operation, which already may annoy some permanently. In addition, the unit will after some time (quite irregular in the beginning and duration) to squeak or creak at. Therefore a star deduction.
Conclusion: Pleasant foot massage at a reasonable price. I do not want to give up the unit.
