This computer mouse becomes very handy to use when you have a lot of work to do on the computer or if you spend longer hours working on the computer. It sometimes become really boring having to click on the key board every now and then when working on the computer especially when using the desk top. My husband bought this logitech V220 Optical Wireless Mouse for us to use at home. I love it so much especially because I like to do online shopping. It is much more easier to click on different items using this wireless mouse than using the key pad on the computer. Also this mouse helps to provide comfort to your hand, by keeping it relaxed while searching on the internet. This mouse makes it easy to navigate the website, by clicking on the up and down botton, without going to the key pad. Also it is nice because you can always carry it with you wherever you go. Durability We have had this one for a long time, and all you need to do is to change the batteries.
