To test the mouse I firstly started up my favourite online game, Counter-Strike and connected to a MOS server. I decided to test gaming performance with Counter-Strike because its mouse movement pattern involves speed, accuracy and a quick response time. I played for an hour with my original Explorer and then swapped over to the Wireless Explorer for another hour. I found that my original Explorer was slightly more responsive than the Wireless Explorer. Now that doesn't mean that the Wireless Explorer is a poor performer, it is just slightly less responsive to fast movements when compared to the corded Explorer. This can usually be expected when comparing a wireless mouse to a corded mouse.
The next thing I tested was performance in everyday applications such as Paintshop Pro, Outlook Express, Internet Explorer, Microsoft Word, etc. As these applications do not require many fast movements I did not find any difference between the Wireless Explorer and the original Explorer in these applications. Both mice were very responsive and I found the scrolling speed option to be very useful when i'm writing/reading reviews.
Overall, I felt that the Wireless Intellimouse Explorer was slightly less responsive when compared to the original Explorer in gaming applications. When the two mice were compared in standard desktop applications eg. Internet Explorer, Outlook Express etc. the difference was negligible.
Finally, I decided to test exactly how far I could stand away from the receiver and still use the mouse. Surprisingly, I was able to stand up to 8ft away and could still control the mouse. I found that at 9ft it got very sluggish and any further than that the mouse wouldn't respond. This is 2ft further than the 6ft Microsoft have stated.
