It may look appealing but this is a new company and I don't know how serious and reliable they are. If you are really appealed by the 1K price for group buy , just go check Amazon, there is a single T9 antminer which is almost same as S9 a few THS less but you can get it as low as 909 dollars so worth a try.And it is quieter too. You can get a used one even for 775 dollars so I think you should check Amazon out.
