So.. still waiting on the refund that you guys said I was due from 2 days ago. No response still.
To anyone else thinking about renting here: I'd steer clear. Rented a large rig, performance was horrible. Tried 3 different (major) pools which he kept claiming were the "issue" even though all the other large rentals were fine on them. Used his pool (which defeated the whole purpose of the rental as I didn't want to mine one of the 5 shitcoins directly on his pool) and still got performance that was less than advertised by a significant margin. Betarigs offered me 10% back.. wow thanks.
Besides the fact that the performance of the x11 rig sucked, Betarigs should have some sort of option to cancel the deal if your main purpose for renting the rigs does not work and the owner doesn't mention it up front. I didn't want to mine BlackCatCoin or Hirocoin directly, but was forced to because this shit rig couldn't handle Blackcoin Pool, TMB, or anything similar. Mind you I have almost an identical amount of Scrypt hash pointed at the same pools and they handle it fine. I don't want to be locked into wasting 0.2BTC because this farm admin doesn't know how to properly tune his rigs.
I would have been 10x better off just buying .2BTC worth of any of the coins I wanted after this garbage experience.
I will also say the support staff here is incredibly slow to respond to any issues, unlike the other rental site that I've used.
