I'm currently using it after paying $500 five times.

I tested it all day long, spinning it around a lot because I was testing, and even if I spin it with opus - extra, it doesn't run out within 5 hours.
I'm a little worried about the weekly limit, but since I won't be using it as much starting tomorrow, I don't think I'll need to pay up to $200.
The conclusion is that if there are no problems, I can spin almost everything I want to do with $100. That's a relief.
