Ordered two. Both of them works well (tested). However both arrived with old bootloader (not a big deal), because you can easily burn a new one (e.g with an Uno). And one of them with a faulty power led. Neither a big problem. I guess it's just an unfortunate and in this price it is acceptable for me.
I received the two ordered Nano Modules today. Unfortunately, the old boot loader ATmegaBOOT is installed. I need to install the current boot loader optiboot. This was not planned and affects my satisfaction. BR Robert
