MicroBT WhatsMiner M66S 298Th/s 5513W BTC Miner

Was a bit nervous about ordering hardware this size online. Acoustically nowhere near a standard Antminer, night and day. WhatsMiner's firmware isn't fancy, but it's reliable. SHA-256 machines all look the same on paper, the hosting cost is what actually decides it. Their installment option is what made the purchase possible for me. Running it under their hosting plan in Iceland, first payout hit on schedule. Would have loved a spare fan bundled in — small nit. Not a beginner box but a great value for the tier.

Came double-boxed with all the accessories. At 65 dB it's tolerable in an outbuilding. At current hashprice the payback maths still works if you have cheap power. Dashboard for the hosted unit shows shares in near real-time, which was a nice surprise. The PSU cables are a hair short if you're rack-mounting. Would encourage a friend to buy from here.

My accountant will hate me but I'm glad I bought it. Acoustically nowhere near a standard Antminer, night and day. WhatsMiner's firmware isn't fancy, but it's reliable. Solo hopes are zero but that isn't why you buy one of these. Their installment option is what made the purchase possible for me. Fair price, honest listing, working machine.

Ended up here because the price was fair. The sound signature is more of a hum than a roar. Draws 5513 W at the wall, matches the plate. At current hashprice the payback maths still works if you have cheap power. Even split the payment across two methods without any drama. No complaints, would order again.

Five stars all the way! MicroBT WhatsMiner M66S 298Th/s 5513W BTC delivers consistent performance. Getting stable performance numbers around the clock. Legitimate business with fair pricing.

Very happy with this purchase. MicroBT WhatsMiner M66S 298Th/s 5513W BTC performs exactly as advertised. Well-built unit with good cooling system. Professional service and authentic equipment.

Bought it during the summer dip in price. Pulling roughly the advertised wattage from the wall. Another WhatsMiner for the Bitcoin side of the fleet. SHA-256 machines all look the same on paper, the hosting cost is what actually decides it. Ordered on a bank holiday and still had a tracking number by Wednesday.

This MicroBT WhatsMiner M66S 298Th/s 5513W BTC is a beast! Power draw is within the specs. Ordered from BullMiners and received it within 9 days. The warranty and support give me peace of mind.

Replaced an older unit with this one. Firmware update pushed on day one, worked without bricking anything. Bitcoin pool is FoundryUSA and shares are landing every few seconds as expected. Invoice was clean and matched exactly what I was quoted. Worth every euro so far.

Satisfied with this purchase. MicroBT WhatsMiner M66S 298Th/s 5513W BTC is doing well mining BTC. Setup was straightforward with the included manual. packaging could have been a bit better but overall great.

The listing was actually accurate for once. Coolant loop is holding pressure and the flow rate matches spec. At current hashprice the payback maths still works if you have cheap power. I emailed the ops team on a Sunday and got a reply on the Sunday. Would encourage a friend to buy from here.

This replaces a very tired old rig. Would recommend to anyone with cheap power to burn.
