Look elsewhere
The pressure and massage/warmth work great. The design however is terrible, but I guess you get what you pay for. The AC adapter plugs into a small cable coming out of the back of the unit. When in use, the cable easily pops out over and over again, which results in constant readjustment instead of just relaxation. Also, for some reason, my device stops sporadically and I have to lean off of it for it to start again.
