What is this model in/where can I get one?

Also, just to be safe: everyone understands that this is not really suitable for self-bondage, right? Once in, you won't be able to get out on your own.

Though, I doubt you can actually get in on your own too.

Electric winch, remote control, panic snap for emergency "lost power" release. Then you only have to worry about how to lock the remote away for a specified amount of time.
