same. It's brilliant and I pay them nothing.
I tell friends and family about it all the time, but I can't seem to convince anyone to use for it every subscription like I do.

Currently thinking of the ways of pushing this down even further by living in an anti-squat. Hacking is the only pathway to inner independence.
