  1. Rated 5 out of 5

    B8 units works as expected, it runs close to “ideal” temperatures and within specs for expected performance. Have bought several here with no problems. Been running two weeks from 1st Feb so far. Be very very careful about overheating in living room. Garage or basement are best place for this device!

    WARNING! WARNING! WARNING! Only three words about B8 device: HUNGRY, LOUD, HOT. Hungry? In an American household, you’ll have to get creative with electrical circuits to make this work safely, consult knowledgeable people, and expect your monthly electric bill to go up by whatever 6500 kWh costs you. Loud? Like few vacuum cleaners in a shouting match, complete with occasional nails on chalkboard harmonics, your housemates will toss you out on the street with this thing if you don’t address the sheer noise, again consult people who understand acoustics, this monster is NOT intended for inside house use. Hot? Forget about muffling the noise with a pile of pillows unless you want a $7000 bonfire, and possibly your entire house, 200+ CFM of ventilation is a good start, and make sure all that hot air goes somewhere both safe and away.

    That said…I’m having a blast with this thing, its working incredibly well and almost-solving all the issues with this behemoth has been a very fun challenge it itself. I’d buy another one or two if I didn’t want to redesign my house to make living with more than one livable. 10/10.

    Just received it, (order on the end of Jan) Looks good but really noisy for private use…
    Which pool is best ? Is it better to play solo for optimal return ?
    thanks for your advice

    This is by far the best SHA-256 miner on the market. It’s all in one, so no extra power supply or control board is required. Very easy to set up. I did however expect a higher gas rate but all in all keeps steady around 45-47 TH.

    4th Estate

    When it first starts up the fans go automatically to full speed and it is really loud for a minute or less. The fans will then go back down to a more normal and quieter speed shortly after. I bought from CryptoHardware and they delivered longer than expected but it’s ok. Perfect condition.

    I highly recommend to buy an uninterruptible power supply and ventilation system for this machine.
