We all know wireless kinda sucks, or at least it did the last time we checked but I kinda have a shitty experience using a PS/2 to USB Adapter and even as I was typing this sentence, my keyboard browned out three times and that happens all the time. I heard back in the day, Bluetooth used to have connection issues and it has newer power saving features and better solutions were proprietary RF receivers, (of which had their own problems) but that's changed in the past few years. Still, it's hard finding good Bluetooth Gaming Mice. It's no big deal to get a USB or PS/2 Keyboard and use a Bluetooth transmitter as long as the connection is stable and responsive, but it's hard to find a Bluetooth Gaming Mouse because people that look for Gaming Mice are very picky when it comes to the Sensor and the Mouse Acceleration and often find a good mouse as for the electronics, but has a braided cable or has a shape not suited for their hands.
But those were general complaints about input devices in general, so what is your recent experience with Bluetooth for Gaming?
