Frequently Asked Questions
Customer Reviews
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.
This ASIC represents the current pinnacle of mining technology. The efficiency, the stability, the build quality - everything is best in class.
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.
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.
