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.
Good miner all around. No major issues and the performance is solid. The web dashboard could use a refresh but the hardware is great.
Best mining investment I've made. Quick ROI compared to my previous rigs. The build quality is top-notch and the cooling system works great even in summer.
I've owned miners from every major manufacturer and this is the one I trust most. The uptime and stability are in a league of their own.
This is my third purchase. I keep coming back because these miners deliver exactly what they promise. Stable, efficient, and well-built.
