I would not buy any gear from Strong U
https://amp.reddit.com/r/BitcoinMining/comments/ejhve5/my_small_operation_of_strongu_u6_machines_warning/It seems they are close to same shit level as Ebit.
But I'm worried that even if I write anything,
still guys will order from companies like Ebit and Strong U.
The market is so hot right now that people are ready to buy even the shittiest gear available.
I know that FOMO (Fear Of Missing Out) can be a strong feeling,
but always think twice before investing money on mining gear.
