Holds temperature great!
My old foot bath finally died after 15 years, so I bought this one as a much needed upgrade.  The 'water rain shower' feature for your legs is really just that, a very light shower that you don't feel much of.  Shiatsu?  Nope.  The roller balls under your feet feel pretty good, but you have to hover your feet above them otherwise they stop rotating under any slight pressure, so your legs are working instead of relaxing.  The walls of the tubs are quite tall, which makes a nice deep bath, but that also means you have to sit a little higher than your recliner in order to get your feet into the tub and onto the rollers, and then keep your feet hovering so that the roller balls can spin freely.  I did not feel any 'vibration' nor water pressure/flow on my feet or calves.  It does hold the temperature very well - after 20 minutes it did not drop the temperature at all, but the ad is incorrect in stating that it will heat up to 118 degrees.  It will only allow you to heat up to 108 degrees.  Anything above that I would think could be dangerous to your skin or blood flow anyways!  The timer works fine, and the drain hose is a nice feature, and it has rollers so you can scoot it around the floor easily, but that tub gets very heavy when filled.  Oh yeah, the pumice stone - a very rough volcanic-looking rock on a little piece of rope.  Don't use it, it tears your foot up!  Pumice should be very fine and smooth, not craggily and jagged with 1/4 inch holes in it.  Does this unit work as stated - pretty much, but I think they could have done a little better with it.
