Summary: Might not have the best specs, but for it's price (I got it for around $30 back in the day), it's very nice. Much more comfortable than the deathadder.
Pros: VERY comfortable for people with bigger hands (guy hands, wouldn't recommend for most girls). On the fly DPI settings is very convenient. Despite what people say, it's not that heavy at all; in terms of actual weight, Razer Deathadder is noticeably heavier. Flat surface scroll wheel makes it easy...
Cons: None. Although while I was using another mouse and had this in storage, the mousewheel somehow got sticky... rubber may have melted or deteriorated.
Summary: Still going strong and takes a beating after all these years so I am quite surprised. Logitech makes some nice mice but none have outlasted this thing. I never like to say anything nice about Microsoft but some of their gear does stand strong.
Summary: This otherwise fantastic mouse has a serious flaw: the rubber mouse wheel turns to goo after around 12 months and became virtually unusable by month 24. Also, right out of the box the indexing notches for the mouse wheel were not very firm and before too long the wheel started slipping between...
Disappointment - but maybe I should have been more specific when shopping.

Summary: Does not have optional weight compartment like my old sidewinder mouse, nor are the feet replaceable (that I can discern). Might be solid for a new gamer, but it's too light-weight for me. The inability to replace the feet when they wear out doesn't bode well for longevity.
