Frequently Asked Questions
Customer Reviews
I bought this miner on a recommendation and it was the best advice I've received. The unit outperforms my expectations daily.
Works as advertised. Hashrate matches the spec sheet and power consumption is within the stated range. Honest product from an honest company.
Average performer. Does what it says on the box but nothing extraordinary. Power consumption is a bit higher than I expected.
Mixed feelings. The hardware is good but the software feels like an afterthought. Needs a serious UI overhaul to match the quality of the physical product.
I was hesitant to spend this much on a miner but wow was it worth it. The efficiency is game-changing and the stability is remarkable.
Good miner all around. No major issues and the performance is solid. The web dashboard could use a refresh but the hardware is great.
