Onyx - yes you can save but the aliexpress models are not genuine.
While some of these Chinese knock-offs actually work perfectly fine (I have one that I am currently doing hardware mods on for a friend, and cant tell difference between it and my genuine hardware testing both low and and high frequency functions). A lot are non-functional and come with a plethora of issues due to lack of quality control and lack of quality components.
You are playing basically luck of the draw when buying a PM3 from eBay or aliexpress. I have a 2nd knock-off unit from eBay that basically just wont function, it sometimes reads LF and always reads HF but can’t handle any high frequency attacks (crashes every time) and it cant write to a t55 chip consistently.
