Q: I've been searching for a replacement to my Microsoft Wireless IntelliMouse Explorer 2 that can take advantage of new features in MS Windows. This mouse _isn't_ it. I find it's not as customizable and it's uncomfortable in my hand. I also dislike the lack of bio-feedback on buttons. I'm continuing my search.
A:
Disappointing replacement to Original Intellimouse
