I'm impressed. I've been mining for 5 years and this is one of the most reliable units I've owned. Zero downtime in 3 months.

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.

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

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