I was satisfied with mine the one time I used it, but my team at the time made me aware of the “sudsy runoff” issue. While at first I thought not much of that, imagine 1000 or more campers dumping their waste willy-nilly all over someone else’s place.
The students loved it. I’d assigned them a short writing on a memorable trip, so I showed them one of my writings on the ride – and that video. One student wrote how she worked in Las Vegas but had never really seen it till her beau rented a hotel room there and showed her around.
