Summary: I though that buying a mouse from the Alienware range would be a really great experience but it was DEFINATLEY not the case. First of all the scroll wasn't working properly , I had to scroll like mad for half an hour to get it working right.Since then i didn't had problems with the scroll.Must have had something with the inside mechanism that was in the way of the optical scroll sensor.
Summary: After using my old alienware mouse for a year and a half it stopped working so I bought another one hoping it would last more. Overall the mouse is the best I've seen and it is very comfortable while gaming especially with the dpi switch allowing you to control speed.
Summary: 2 years after purchase, the left mouse button died (double click instead of single click issue). It was a great mouse while it worked. For £40 I expected a little more for my money. Alienware isn't what it used to be since being bought by Dell.
Summary: Have owned and used this mouse for 18 months. It certainly gets the job done, and looks nice, but a few things let it down imo: 1) Laser tracker stops responding correctly if a single hair or strand of lint enters the laser area, which is fairly often. Also if anything gets in there, it's not easy to get out. 2) Side mouse buttons could be placed slightly better, and be more responsive. Only a minor complaint here though. 3) Cheap build quality.
