Well Made Unit [SEP] This is an extremely well-made unit and appears completely waterproof.  It charges in about an hour with a charge that lasts me four showers.  While it removes some skin I would prefer stiffer rubber “bristles.”  The handle is made of a slippery plastic that is impossible to hang into with soapy hands.  Probably OK for the bathtub, but risky in the shower.  Men usually have larger backs and are less flexible.  So I made a longer “handle” with a 12” PVC pipe, attached with a gasket and a hose clamp, easily removed for charging.  The pipe also doesn’t slip in a soapy hand.  With all the running gear in the head the unit is top heavy when in the charger.  Even the suction cups on the charger base can’t hold it upright.  However, the gasket for the handle also pushes the unit enough off center to balance it and prevent fall overs.  The instruction sheet is a riot.  It reads like it was run from Chinese through a translation program into “English.”  The best line is “Especially designed with horny brush and thus removing residual horniness.”  If only it were so simple!  It should be rewritten by a native English speaker.
