how often do you replace your computer mouse?  

every year, the computer shop where we bought this give us free mouse

I use a wireless optical mouse for 3 years. Maybe if it is defective and no longer unusable, I can replace it.

I use optical mouse since 2 years and do not disturb. Wireless mouse I use not often as it is in my office and use by other co-partners. I have a mouse Acer which is working from last 6 years with Acer PC but ordinary ball mouse and use 5 days a week huge time each day!

i use a small optical mouse too, it's very comfortable,very good

I use an optical mouse for more than 3 month , and I use wireless mouse for only a few days .

I'll not replace my mouse, instead i clean my mouse so often..otherwise it will get spoiled..so cleaning is better option than changing the mouses according to me.. are you happy in changing the mouses instead of cleaning it? i cant afford to that.

I've never replaced mine! I want one of those "hand warming mouses" though, oh, that would be so nice!!! I wonder if they have those in the optical ones?!?
