With mice in mind, my word of advice is that if you don’t have a mouse that feels comfortable, you should help the economy and splurge on one.
Why you ask? It’s just a dumb mouse, aren’t they all the same?
They aren’t. Some track better, have more buttons, are wireless or have other funky features… but that’s not the important part.
Side note: If you look on the bottom of your mouse and see a little ball recessed in the mouse’s body, go out and get an optical mouse. I’m not kidding, you won’t miss the little ball. I promise.
What matters is that your mouse feels comfortable to use. If you are anything like me you sit in front of a computer for obscene spans of time. Why be uncomfortable? If your mouse doesn’t feel right, you can injure your wrist, or cause neck and back pain. Get a mouse that works for you, and maybe a wrist wrest to go with it.
Practice safe computing and avoiding injury.
