Overall and FV
My experience with the M60 and M90 was much like my time with Corsairs K60 and K90 mice. With both they found ways to make me wonder why more companies don’t do things. On top of that they managed to make mice that just scream quality with a good portion of each being made of Aluminum. This is a far fetch from even the best mice on the market where most are made out of plastic and share the same design features. All of my complaints are small issues, and are almost all related to the side buttons on the M90, but if you don’t lift your mouse and don’t mind reaching for a few buttons you will be really happy with ether choice. But considering the lower price of the M60, unless you actually need the addition buttons or glowing Corsair logo you can save a few bucks and have a top level gaming mouse.
