Just bought a uO_C from @PinPinKula
Comunication:
PinPinKula was always very quick to reply, and was very helpful.
Shipping:
After the payment went through, i received the tracking information for the package.
The module came very very well packed, i have never received a module this well packed before (either from marketplace or shop purchases). It came nicely packed with lots of protective bubble wrap, and snug inside the box (not too tight and not loose).
Module Quality:
As for the build quality (this is a DIY built by PinPinKula) the module is professional quality build. Never have i seen such a flawless job (human made). I can do some DIY builds and know how much care is needed to build a module by yourself.
I really recommend buying from PinPinKula if you want quality.
If a compactflash card could talk, it would say "yes".
