Pros: Durable, Easy to Use, Quality, Good Value, Comfortable, easy to clean
Excerpt: In having to use a mouse daily & all day at work I was suffering shoulder pain quite a bit - a coworker said she had same problem - discovered that using the track ball mouse was the answer - I was very skeptical but I bought one - this was the best thing to buy - shoulder pain has gone away - this is the best.... but not everyone likes it... other coworkers say no way - so I have the regular mouse as a spare for them.... Don't take away my trackball!
Pros: Durable, Easy to Use, Quality, Good Value, Comfortable, compatible, adjustable
