Yeah this is actually my 3rd one. The previous two developed a double clicking problem and were replaced under warranty. The most recent one the middle mouse button stopped working intermittently. When I took it apart I found that the button itself worked fine when I pressed it directly or even with the wheel as long as the screws were loose, I suspect the plastic peg that presses it when you push the wheel was worn down and no longer hitting it right. Fortunately I had the previous one it replaced still and was able to just swap the top halves on them. I'm seriously considering buying some switches to see if I can fix the old one too to have a backup. I'll have to figure out the middle click problem too but I have some ideas for that. All that being said I'd just fucking buy one if a replacement was available.

I'm glad you at least found something that works for you. I've got a no name wireless keyboard and mouse for work that were the only set I could find with both a mechanical keyboard and regular batteries. It's always a gamble but sometimes those no name brands are surprisingly decent.
