Are you talking about KncMiner?
Yeah that was a disaster, at one point I was glad that there was a manufacturer right in the neighbour country but I'm glad that I stayed away after all and have bought mostly Bitmain and Canaan Creative (Avalon) gear.
No i was talking about https://products.butterflylabs.com
Another company that is no longer alive apparently. It used be back then people had to wait for pre-orders while the difficulty was jumping all the time. Can't believe how much crap people come up with whatever they do.
Their miners were also shit by the time they arrived, I collect them as of now just for my little USB miner collection but they're generally not the most reliable. Their monarchs were quiet and relatively nice for mining with efficiency around that of the S5 or SP20 underclocked.
AMT was also a pile of shit that people never got their money back from; if you did get a miner, it was pretty much a LKETC dragon miner assembled somewhere in China and sent to wherever you lived.
