It does the job as described on YTube videos.  The instructions are odd, try reading them vertically, they will make more sense (really).  The suction cups are oddly angled, til you put the unit in the tub, then they make sense.  Too bad the instructions have not been updated.  Bring the manufacturing back to the USA and Canada, we'll clean that right up!!  It was a smart purchase, wish I would have learned about it sooner.  Regards, H
