My wife needed one after she broker her wrist, and had some issues. We’re on our second one (the first one broke, and was flopping around under the seat…), and it’s the one reviewed. Luckily, we live in Florida, and so our water is definitely warmer than were we grew up, Ohio, and it’s not much of a problem. Even connected to a hot water line up north like Ohio would be a problem because you’d already be clean by the time you got to any hot water.
Full pressure first time? It’s a wonder you aren’t bleeding!
