Got my hands on to Promax 7.2, its huge and looks rock solid, weights heavy, took two person to lift and set on table. I wanted to open and see whats inside, but couldnt do as it would void the warranty. The setup guide is simple, once I booted the device it took about 10 seconds to start the miner. All I had to do is add the stratum and my eth wallet address along with decred wallet address on dual mining mode. Initially it started showing 3.683 Gh/s but eventually after 20 minutes of mining the counter got settled at 3.704 Gh/s. The performance till now is astonishing and I doubt if anyone have ever build such a mining monster. Will share my further reviews of overall performance sooner.
