OK, I bought a white Dottie, it came today; I put a white Dot in, and it's in our master bath, top socket of wall plug. Easy setup; it has a snapped in PS w/short power cable. It all fits in place in outlet, including the night light with aid of a three-socket wall tap in bottom of wall plug. hopefully, the PS and power cable are quality ones that will last.
Thanks again to OP for alerting us to this handy new gadget. Next time I am at our nearby Amazon Store I will recommend to the manager they stock some in their store.
