Frequently Asked Questions
Customer Reviews
It's a competent miner. Does what it says on the spec sheet. Not exciting but not disappointing either. The Toyota Camry of ASICs.
It's a miner. It does mining things. If you need a basic unit that won't give you headaches, this works. Don't expect to be amazed.
Good miner for the mid-range segment. You won't find better efficiency at this price point. The value proposition is hard to beat.
Best ASIC I've ever purchased. Period. Every aspect from delivery to daily operation has been flawless. This is how mining hardware should be.
Average miner with average performance. Nothing particularly good or bad about it. It exists and it mines. That's my review.
Five stars without question. I've been mining since 2017 and this is one of the best ASICs I've ever owned. Reliable, efficient, and well-supported.
