I hate it when rubber becomes sticky as it ages. My 18000 mAh power bank still works perfectly, but I don't want to use it because the surface feels disgusting
@volpeon Worst thing is, that kind of soft rubber coating is on so many peripherals now like mice and keyboards. Sure it feels great in the first few months, but after that you can usually throw the device away.
Bottom case part for a Logitech F710 wireless gamepad. With battery cover.
Because mine turned into a sticky goo after the years, I 3D scanned the case and created one in blender from the scan.
