I think I'm going to buy 4 T9+. I have 4 good coupons.
hashrate /price is good but require double the power.
I am also considering the T9's provided the price right now. What do you mean by double power? Aren't they the same power as S9, but just lower hash rate (and supposedly more stable).
I think he means that as you need same power to have half less hasrate, you need around 2x more power to match S9 hashrate. So it's ok if you have good electricity price.
I can
can vouch for the T9 (first model 12.5 Ths). Have units since the first batch was released (some were never turned off since Feb 2017), faced no issues so far (knock wood), same power supply, just opened once for cleaning. They generate more heat though and consume more power.
