Customer Reviews
Decent miner for intermediate users. If you know what you're doing, you'll get great results. Beginners might need some help with setup.
Very happy with this investment. The miner runs 24/7 and barely needs attention. Just clean the dust filters monthly and you're good.
I bought this miner on a recommendation and it was the best advice I've received. The unit outperforms my expectations daily.
I was hesitant to spend this much on a miner but wow was it worth it. The efficiency is game-changing and the stability is remarkable.
Good miner all around. No major issues and the performance is solid. The web dashboard could use a refresh but the hardware is great.
Average performer. Does what it says on the box but nothing extraordinary. Power consumption is a bit higher than I expected.
