So far so good. Running for six weeks without issues. Hashrate is consistent and the pool connection has never dropped.

Very satisfied with the purchase. The miner arrived quickly, was easy to set up, and has been hashing away ever since. No nonsense.

Efficient and Quiet. I love this miner! The efficiency is impressive, and the noise level is lower than other models I've had. It runs smoothly and I can leave it on for hours without worrying. Highly recommend for serious miners.

Honest review after 6 months: it's decent but I had to replace a fan already. The miner itself is fine but the accessories leave something to be desired.

Impressive little machine. The efficiency numbers are real. My only suggestion would be to include better documentation for advanced settings.
