Frequently Asked Questions
Customer Reviews
Temperature never exceeds 65C even in a room without AC. The cooling solution on this miner is world-class. Very impressed.
Decent miner for the money. Not going to set any records but it's been running fine for months. If reliability matters more than peak performance, consider it.
Absolutely recommend. I've tried many miners over the years and this one stands out for its efficiency and reliability. My go-to recommendation.
The pool connection has never dropped once in 6 months. Rock solid networking on top of great mining performance. Underrated feature.
The efficiency king. This miner sips power compared to the competition while delivering the same hashrate. My electricity bill thanks me.
Average miner with average performance. Nothing particularly good or bad about it. It exists and it mines. That's my review.
