Absolutely brilliant. Easy to set up, quiet operation, and the efficiency is incredible. Makes my old mining rigs look prehistoric.

Good miner all around. No major issues and the performance is solid. The web dashboard could use a refresh but the hardware is great.

Mixed feelings. The hardware is good but the software feels like an afterthought. Needs a serious UI overhaul to match the quality of the physical product.

Very happy with this investment. The miner runs 24/7 and barely needs attention. Just clean the dust filters monthly and you're good.
