This Dell mouse... is a rather average mouse, as in, it is exactly what one would expect from a fairly cheap mouse.
I've had my mouse for atleast 3 and a half years now and it hasn't worn out in the slightest. For me i can't live without a mouse with a scroller.. which can also click to "open in new tab".
The use of colours is great; as the black and silver suit the colours on my computer, in my opinion.
The chunkiness of the mouse makes it each click harder and more defined so that you never accidently click more than once.
Although, it isn't anything special either - unlike some of the latest mouses on the market - this isn't wireless and is a simply shaped mouse. Even so i do very much like it and would recommend it to anyone. Furthermore it has rather new technology, on the underside of the mouse, the Dell optical mouse has a red light (which is a sort of sensor) unlike the old ones, which had a little ball rolling around, the problem their was you had to clean it every so often and it got stuck.
Most importantly IT WORKS
