It's a fine pool and it's rock solid as far as uptime.
The only thing that I'm a little sore about is being dumped into the crappy end of the pool during a run of bad luck with no notice.
Here I thought I was hashing along fine the last few days, only to login after the weekend to find my earnings on a portion of my farm is in the dumper...and it's the portion that I use to stabilize variance.
Shrug. I'll get over it. Other than the lack of notice. It's great pool and one of the few that I do trust.
