Two ways of running a session are built into this massager, and they suit different moods. The automatic program holds 4 preset modes and needs nothing beyond a button press, which is what most evenings call for. The personalized program hands back control of speed and direction, so pressure can be pushed harder into a stubborn arch or reversed when one rotation feels better than the other. Both are driven from a handheld remote, which is the only sensible arrangement once both feet are already inside the machine. What the machine does with that control is firm work rather than surface buzzing. High intensity rollers press into the soles while the two open sleeves take in the calves, so a single session runs from the toes up to below the knee instead of stopping at the ankle. The sleeves accommodate a US men's size 10 or women's size 12 foot and a calf circumference up to 15 inches, which covers most adults in a household. Construction is ABS over foam and fabric: a rigid outer wall to take the load of the rollers, and a padded surface where the skin actually touches. The foot sleeves open on a smooth zipper, come out completely, and go in the wash, so sharing the unit is not a compromise. Four foot mats on the underside stop it traveling across the floor while the rollers work, and built-in handles make the 15 pound body easy to lift out and put away. It runs at 40 W on 110 V, measures 23.5 by 13 by 9.5 inches, and arrives in Gray with a remote control, a certificate, and an instruction manual.
