Auda dear, I obviously didn't take a dump in the middle of the open showroom... they have the bidets installed in the toilets, so while the sales guy was harping at me on the other side of the cubicle raving about features eg heated seat, soft close, automated, LED light, bluetooth etc., I meticulously inspected and test drove each one. I complained they weren't strong enough and lacked precision so he demonstrated with his fingers the width of precision for their special bidet. This one apparently was so strong it hurt his butt hole for weeks. So I've bought it and will have it installed next week. I'll let you know if I go tender like he claims, but I highly doubt.
