Human Touch Sana
The "L" bracket design works extremely well and makes a big difference massaging the lower back. The numerous massage modes provide lots of variety and can be focused on a particular area. I especially enjoy the lumbar heating element. The lower leg section does not work near as well and I don't find it useful. More control over the air pressure in the air bags would be a big improvement. Would be nice to separate the various areas, e.g., different pressure for the feet versus the calves.
