I was appalled at just how much dust and hair had gotten beneath the keycaps!

I bet!! Haha. 😅 I really need to clean my keyboard... it's backlit so I can see a bit of the dust that's lurking under there, waiting for me to find it... ugh.

That new mouse looks fantastic! I have the Logitech G302 and I love it so much, it's so light and it fits in my hand perfectly. My partner has your old mouse, the G502, and I have no idea how he uses that thing. It's so heavy and clunky and large. xD I'll have to keep the Pulsar Xlite in mind whenever I go mouse-hunting again. 😁
