Pros: Replaced my old MX518 with this. I am very pleased with this mouse. Every feature the MX518 had this mouse improves on. and its really not as ugly as the pictures make it seem

Cons: none so far

Overall Review: Make sure you download the software from logitechs website. It will allow you to program the buttons and adjust dpi. I guess if I did have a con it would be that mine didnt come with a driver disk (which isnt a big deal)

Comments: well so far its running just fine it is a little loud buy not too loud. i normally buy western digital harddrives but since this one was so cheep i couldnt resist and i need the storage space ASAP

Comments: i cant believe this thing is that good. it is tiny and it weighs quite a bit for as small as it is. i have a 2500+ overclocked to 2.2 and this thing keeps it kool at 34c and load is abotu 42c very nice oh and it is very quiet

Comments: good fan blows more air than my antec fan. bright leds the only thing was that when the fan is off it looks more orange but as soon as i turn on my computer its blood red

Comments: the fans are maybe a little loud but the red leds are nice and bright. blows plenty of air! and as always newegg is the best!

Comments: this is a very nice heat sink. i have a 2500+ barton overclocked to 2.2 ghz and it idles at 39C and my thermal plaste is not even that great. i recommend arctic silver 3. buy this if you plan on overclocking it works good for the price
