Is Canaan Avalon Nano 3S REALLY Better Than Nano 3?

Canaan Nano 3 had so many fatal flaws one of which is the 4R7 SMD power inductor resistor that sits just in from of the USB C power socket. With the high heat build up in this part of the PCB, the paste used to secure the 4R7 SMD becomes brittle and the resister breaks contact with its two solder points on the board, this can lead to the fatal error message "non Support Adaptor", Nano 3 vs the latest Nano 3S, lets hope Canaan have dealt with the power supply and Wifi problems experienced by so many.
