This is an above medium quality product for sure. The material used -solid aluminium frame and quality plastic- are giving a flair of premium to the M60. The mouse sides have a rough texture while the top is smooth and soft. The weighting system might not be fancy but it does an adequate job if you want to fiddle with balance and weight. The Teflon legs are great and the mouse glides exceptionally both on cloth and hard surfaces. As a minor complaint I would like to see extra Teflon stickers in the packaging. Mouse design is ideal for Claw, good for fingertip (slightly difficult on reaching the sniper and forward buttons) and average on palm grips.
The only think that can set you back from buying this product is the accompanied (or not since you have to download it) software. First of all Corsair promotes the use of firmware updater, since it includes the tool with the software download. Then it prompts you to update the firmware in order for the software suite to work (first time ever that I have seen something like that). But its unacceptable to not support USB 3.0 ports FOR THE FIRMWARE UPDATE procedure. If you try to do that, as I did (No USB2.0 on mobo), you are going to have major issues, that if you are not an experienced user are going to escalate to RMA. Overall the mouse configuration software is cumbersome and needs some rethinking. It is like its trying to scare you away, specifically if you are going to use macros.
To sum up, its a great piece of well designed and implemented hardware. Highly recommended but if you are not an experienced user avoid to update firmware alone, nevertheless Corsair got you covered fellow gamer.
