Pros: The Sentinel Advance II is such an improvement over the SA I. It will do anything and everything I want it to in any game I play. From WoW to SWTOR to Skyrim. The buttons add a level of ease to my gaming experience, I am so glad I gave it a try. Thanks again Cooler Master and Newegg!
Pros: After having the my original Cooler Master Sentinel Advance wore out, I looked at different brands and tried a lot of them too, none of them fit my smallish hand better except for my Old Logitech MX518, now the Logitech G400.
Cons: Of course the software can be difficult at times but once you get your profiles dialed in and saved to the mouse's memory you never need the profile manager software again really.
