I needed another corded mouse and this time around I thought of @PKL@mastodon.social and @pronk@mastodon.social instead of Logitech's shareholders. These guys make open source mice among other open source hardware under the brand Ploopy. You can order one from them, assembled or as a kit, or you could print and build it entirely by yourself.
The mouse itself is pretty great. Coming from a long line of Logitech (MX518/G5/G500/G502), it's a bit larger than what I'm used to but I think I'm getting accustomed to it.
Here's another shot of it:
I like it. The surface finish is obviously not as nice as the Logitech, but I like it. I'd probably like it better if it were smooth, which I might try achieving with some epoxy paint. The button feel is great. Better than my G502. Tracking is stellar. The shape is comfortable. The infinite/togglable scroll wheel on the G502 is sonething I wish it had but I can live without it. There's also that special feeling, that someone decent made it, and that it can be infinitely repaired. If it's not a stretch money-wise for you - get one. In the worst case scebario your money would have gone supporting open source hardware.
