Pros: Good dpi2200 very smooth and presice. Hardware instal was easy good size fits hand nicely. switching dpi is esy on mouse with led indcator

Cons: Wheel feel flimzee and has a short cord so if your comp is very far you'll need exstention

Overall Review: I wanted to buy one with a highter DPI but have found that i have to keep it 800dpi in UT2K4 or its to sensitve multi fire mode not usefull in games i ply but nice to have

Pros: Dropped my cpu's temp 20degees!!! fromm idle of 51 to 31 and from mid 70's to 40's under heavy load. Very quiet compared to stock. HUGE heat sink!!!! fitt fine on my abit ag8 mobo Looks cool

Cons: little hard to put in but still only took 15min. Huge heat sink!!!scary wasnt shure the board would hold this masive thing!

Overall Review: Running Presscott P4 3.2 overclocked to 3.5 only raises temp 2 degrees. No problems up to 4.0 before my ram got hot chip was still well within the right temp zone. If you have an old p4 that you want to over clock this is the one for you (If liquid is to much $$$) running 4case fans
