I've worked at a few places over the last few years and have encountered Lenovo, HP, Dell, Kensington, Logitech and Microsoft keyboards and mice - wired and Bluetooth, but the place I've worked at for the last 8 months uses Belkin Ergo mice, (alongside crappy Logitech M525 mice for the users who want a wireless mouse) - I had never seen these before I started this job and they are not widely available in Canada. We buy them from CDW for roughly $10.

After 8 months of daily use (and watching others use and abuse them), it still blows my mind how sturdy and comfortable they are for the price.
I've had plenty dead/broken Logitech mice show up on my desk, but I can't recall any of these mice randomly dying or breaking in any way.
I'm hoping I'm not the only one here who knows about it because it absolutely nukes any other budget mouse under $25 that I've encountered.
