My puny USB connection became unstable after a few weeks, though I had been very gentle with it. I decided to get a replacement unit while under warranty instead of opening it up to modify it. When I received the replacement, first thing I did was to insert cable (gently) assuring there was full contact and then... Hot glue on the plug and a piece of gaffa securing the cable - less prone to wiggling. Not pretty, but effective. The G10 is too good an item, too bad with the lame Micro-USB soldered directly to the PCB. Really bad design.
