I got 5 Nano 3 with their PSU.
All running on high for months with no problems.
The new mini 37.5 TH/s looks interesting
Mine were good for 6-7 months they are dead.
Yours will likely die before july
I just got mine second hand and are planning to run them on high. So you mean the USB jack will not last? Just solder on another one or even change it to a barrel jack? The hardware itself shouldn't be "dead" at all. These ASIC chips are usually VERY hard to kill and work under lots of heat in industrial settings.
