got my x10's from 2nd batch yesterday, arrived in promised time frame. Monitored Shipping process, took 3 days from china.
Had to deal with the miner down issue a few times because of deleted pools but was always able to bring em back online with proper backup.

One hashboard of a miner has only 48 out of 64 chips active which is a bit of a bummer.. resulting in a ~8% decreased performance for this unit - contacted Support, awaiting reply.
Otherwise all running stable since 24h now with static IP set over Router and a 2200w murata PSU powering both (yea, overkill but got it cheap..).

First Asic's for me in the mix while mining with GPU's and Cloud - profit is pretty decent, so far no regrets.
