Personally. I wouldn't buy one as Sidehack is just about to release a BM1384 miner with better efficiency and hashrate in a pod form, but good luck with your miner; the connectivity issue is way bigger than it seems on paper. That's what deterred me from buying one.
Thanks allot for the update. I was just wondering if another version of the Antminer U3 wouldn't come out soon, since the only way of buying one seems to be second hand from Germany. Do have any idea of when the new BM1384 will be released?
