I've had no problems with this site. So far everything's worked out a-okay for me. It's early days at the moment though, so I'd strongly suggest not going over 0.25, +/- 0.05btc, the pool needs to get bigger before larger transactions become feasible.
It's been a little slow, but that's because of a lack of 'investors'. The Moderators have been very helpful and show you respect if you show it to them.
I like that it's a sustainable system though, they have 18btc in a reserve wallet to help them meet the 12 hour guarantee time for larger orders (but like I said, needs more 'investors' before it's safe to do larger orders).
They have a priority list, with low volume transactions at the top, medium volume ranges from medium to high priority, and larger transactions at medium priority. The max you can send in, IIRC, at this time is 1btc. A bit high I think this early in the game, but by all means go for it.
I'm fully aware the guy with one post and who signed up only a little time ago will probably be looked at with suspicion, but you have my word that as of now, it's been working for me.
No response from owner\mods again. No payments made recently either. More problems?
