How to Buy a Mouse

Whether you're buying a mouse for a home-built PC or replacing one that is wearing out or dead, you need to get a mouse that is compatible with your computer.

Things You’ll Need:

Step1 Buy a mouse with a rectangular serial connector if you have a very old PC.
Step2 Get a mouse with a (round) PS/2 connector if you have a PC manufactured after 1994 (including all Pentium and newer computers).
Step3 Buy a mouse with a USB connector if you have a PC that has available USB ports and you want a faster response from your mouse. All Pentium II and newer computers have USB ports.
Step4 Choose a mouse with a round serial connector (also called Apple Desktop Bus, or ADB mouse) if you have a Macintosh with a mouse connector built into the keyboard.
Step5 Select a mouse with a USB connector if you have a Macintosh with USB ports (G3 and newer machines). Make sure the package says the mouse is Mac-compatible.
Step6 Buy a mouse with extra buttons for increased ality and productivity.
Step7 Look for a scroll wheel between the mouse buttons if you spend a lot of time using word-processing or spreadsheet applications or working on the Internet.
Step8 Avoid replacing your mouse again by buying a mouse without a rubber ball. Expect to pay considerably more for the increased ease-of-movement, speed and durability.
Step9 Compare the ergonomics of various mice. Look for a shape and size that is comfortable for your hand.
Step10 Compare prices, which range from under $10 to more than $70 for varying levels of comfort and quality.

Tips & Warnings

Many mice come with adapters that will convert PS/2 to serial or USB to PS/2.
Expect a wireless mouse to work as well (and as poorly) as any other remote control. Buy one for action gaming or to accommodate a physical need.
Clean your mouse before deciding it needs to be replaced. (See Related eHow.)
 
Expect a mouse with a ball to last an average of 1 to 2 years.
