Frequently Asked Questions
Customer Reviews
Okay miner. Does what it's supposed to but I had higher expectations for the price point. Still, it's earning crypto so I can't complain too much.
The ROI on these units is incredible at current crypto prices. I project full payback in under 200 days. After that it's pure profit.
Good miner all around. No major issues and the performance is solid. The web dashboard could use a refresh but the hardware is great.
My mining profitability is at an all-time high thanks to these units. The efficiency is genuinely impressive and the stability is unmatched.
This is my third purchase. I keep coming back because these miners deliver exactly what they promise. Stable, efficient, and well-built.
I run these units in a colocation facility and they're the lowest maintenance machines in my rack. The facility staff even commented on how reliable they are.
