No offense to innosilicon but I felt safer preordering from Giga Watt, if there are problems I feel like I'll get a refund easier and if it's a piece of shit constantly having problems then I'll have pros helping keep it running. I trust innosilicon not to run off with my money, but I've been burned by pre orders before. Delays, specs different than specified, and yes those that just never deliver. So I trust Giga Watt, only way I was gonna order one of these and sick of Bitmain dominating mining scene.
