Your cheap home PC doesn't have the physical space for another hard drive inside, so you buy an external one and your wireless keybbbbbbbbboard starts acting up when you're backing up.
Seriously, USB 3 devices put out a bunch of 2.4GHz interference and it fucks up wireless gear. Put your dongles on cheap USB extension cables and blutack them to the underside of your desk, I promise you'll stop hating Bluetooth quite so much if you do this.
Bluetooth is still shit, but this one's USB's fault.
You buy a second-hand but still quite new wireless gamepad. It dies unexpectedly at the approximate age of 16 months. There's a listing for a replacement battery on Amazon and a disassembly guide on iFixit, so you take a punt on a new battery and swap it in.
The gamepad's still dead, so you email its manufacturer for A) a repair, or B) spare parts, or C) to offer them even more money to fix it, but they don't provide any of those for a device still sold new today.
Get fucked, Steelseries.
