Opinion on throne auto drainer?

Just like the title says, I want to know what you think.

Personally, I find them really hot, but I find it hard to really say why. In a way, its like a domme is taking money from me, rather than me giving it away. However, it can be pretty easy to loose control with it.

I dont see these getting talked about that often, or honestly that many dommes with them, so I was wondering what the wider community thought of them?
