exactly as advertised, excellent miner but also a power guzzle. without enough power supply or if u live in a country where power is expensive u might end up working on a deficit my current 24hrs daily earning is $7, electricity is $12 so am at deficit of -5. i have other miners covering up on that deficit while working on a solution so its a win win. bitcoin is the future happy mining fellas

The antminer S21 Hyd is a great investment strategy . If bitcoins prices continue to sky rocket then my investment will be totally worth it not to talk of the autonomy you have over your investment with no banks putting restriction on your funds. thank for delivering on your promise Bitminer Market

for some reviews I have read are funny, this is an expensive computer… no doubt about that, but when your using it for the intended purpose it pays it’s self off. Don’t be mad it takes more then a few weeks or days to generate 10,000$+ in revenue. Sometimes it’s because you don’t know what your doing so it doesn’t work right. Very simple computer know what your doing b4 you fiddle with it!
For those who say these are NOT good I beg to differ little, I work on these on a large scale, definitely worth every penny and pays off fast!
