I've used lower-end Dell mice both at work and home for the last 20 years. They seem to be made by Logitech and while they aren't much to write home about ergonomically, have been very reliable.
For instance, the one I'm replacing this one with has worn the slippery pads (on the bottom side of the mouse) completely off. Still works fine, but no longer slides across the desk well. The new-to-me one fixes that - and at a good price!
A gamer will probably want to look elsewhere, however these are great for general-purpose computing.
