Frequently Asked Questions
Customer Reviews
The hashing performance is so consistent I can predict my earnings to the penny. Zero variance day over day. That's engineering excellence.
Honest take: good miner but the shipping took forever and the box arrived damaged. Miner survived but the experience was subpar.
Five stars all day. I've tried miners from several manufacturers and this one beats them all in terms of stability and ease of use.
Solid Performance. This miner is pretty solid. Does the job well.
Mining hardware doesn't get better than this. I've tried them all and this is the one I keep buying. That should tell you everything.
