The efficiency king. This miner sips power compared to the competition while delivering the same hashrate. My electricity bill thanks me.

Temperature never exceeds 65C even in a room without AC. The cooling solution on this miner is world-class. Very impressed.

Seven months in and I've already ordered three more. The first one proved itself beyond doubt. These miners are the backbone of my operation.

The pool connection has never dropped once in 6 months. Rock solid networking on top of great mining performance. Underrated feature.
