"Web order process worked OK. They handled my next-business-day request for faster shipping well and the BidetSpa toilet seat arrived as promised and in good condition (even though the shipped didn't follow the "this side up" completely. Installation was per the instructions. HOWEVER, there were 3 significant surprises that were not documented on the web site:
1. The requirement to ventilate the bathroom while taking a shower to keep the humidity down requires leaving a door or window open or installing a vent fan. A subsequent Email response stated that this is a UL requirement, but the units have been tested under much more severe conditions with no problems seen.
2. A light weight and angled cover cannot be used as a seat.
3. The forward shift in the seat opening, about 4" on our older toilet, is awkward for men.

This can be a costly problem if any of the undocumented "features" makes it unacceptable, as once the box is opened it cannot be returned. The seat is not sealed in plastic inside the box, so opening the box to get the documentation must be assumed to break the sanitary seal and make it non-returnable.
If looking for a Bidet toilet seat, I would shop there again but would request more detailed dimensions before purchasing."
