Received a rather large parcels in which the box was maintained by the bulpack, in excellent condition. Works as expected: - Either without electricity, we start with both feet in and it heats better than slippers - Or one branch and you press the button and this heater heating, but not too strong, fortunately - Or is connected and press the massage button. Here, as often for Shiatsu massagers, this is a bit brutal. I would recommend to put thick socks or towels end if one has a little fragile feet. I know someone who uses a piece of sports mats or floor mats camping cut to soften. You can put heating and massage at the same time without worry. Attention also to the cable length, a little short in my opinion (1.2m or 1.5m Max, this is not always enough depending on where you sit, and even worse if you get up without pay attention that this is connected!) All in all, a good article for what is asked, perhaps a little expensive but it must be linked to the massage function with the engine.
