I have longer ever looked at amazon for such devices and could not imagine really if this works and the strength of the massage is also sufficient to me. Since then a device was even at Saturn so to try and I was from this moment recently really excited. I ordered the unit immediately. I stand all day and much as these massages in the evening truly a blessing. The balls are really hard, rotate optimally and knead your feet with neatly. Certainly, the footprints are too large - BUT I "wander" with the feet on the different zones and so you get optimal all area massaged. I mean as a device for different shoe sizes to produce would be ridiculous - and because the manufacturer has now times on large feet more consideration take- As I said with the "walk" it works well - so you can reach a lot more areas than when the feet only immobilizes it. The heating function is slow going. Cold feet you do not get so hot. Is a very nice feature that is perhaps worthy of expansion. But primarily, the massage is so important. And that makes the device in my eyes really good. I use the device are a 3/4 year and would like to give back in any case.
