I participated in the beta, and found the node controls precise enough to dial out just the right amount of low mids, in a manner which I might struggle to emulate in other reverbs. I like the results I got, but I also have a lot of expensive reverbs, and the beta discount was only an additional £5. I'll probably pick it up at some point, but I'm not feeling very wealthy right now.
I can imagine this becoming one of my main reverbs though.
