As far as I am concerned, the Corsair M95 is a nice refresh to the brand. The simple fact of making the side buttons softer almost overshadows the fact that the M95 is still a bit long for my hand. While I still do have to reach for a few of the nine buttons on the left side of the mouse, the strange way you had to contort your hand to press them on the M90 is gone, and that is a huge step. While I can appreciate the bump up in the Avago laser sensor to the ADNS 9800, for me it is more for the rest of the features it offers over the ADNS 9500 that the old series had some issue with, because 8200 DPI is completely uncontrollable for me.
What I do like is that you can really fine tune each of the three settings of the DPI level along with the Sniper key in very finite jumps on your way up to 8200 DPI, and you can adjust the X and Y axis to fit a widescreen monitor a bit more accurately. I was very impressed that the old LOD issue was fixed, and even setting and using the lowest of the options, this time for the entire test period, I had no issues with it wandering when I did have to lift, and at high DPI, there isn't any drift from slight vibrations from fans or speakers that I have seen in other products.
You then add in the fact that you have a ton of options still left in the software. So imagine this - you keep the default profile as it is, and you have a few buttons that really aren't doing anything at the moment, so that is six buttons that you can change on profile 1. Now add in that you can do all sorts of things to the 15 buttons on the five other profiles you can have access to, stored onboard, with the M95. So if you have a game that requires a ton of Macros, you can set all 81 options to one game over all the profiles. Another way to look at it is you can keep a setup for the desktop and five games. For each of those games, and part of the desktop setup, you can use then in smaller groups and have quite a bit more power under the right hand while using the M95. With all the Macro ability, and the quick access layout of the left side of the mouse, this is really set up for those looking to improve their MMO and RPG games, but this mouse has worked for me in both, as well as laying it down in FPS and flash games. There is no real right or wrong situations to use the Vengeance M95 in, it just works well for all of them.
When the M90 was brought to the market, I was seeing prices right around $80 at that time. Seeing that the MSRP is set at $79.99 for the M95, it is very good for customers. While there were minimal changes made inside, and not much to the outside, the changes that were made make the usage of the M95 much more enjoyable. Another way to look at it is that you are getting a better piece of gear as far as current technology is concerned, at the same price. That is unless you buy direct from Corsair soon, because they have a $24 discount off that when you add the Vengeance M95 to the cart.
For right around $60, the improvements found in the M95 over the M90 would make me want to pay just to swap out that mouse. If I had something a few years old, the Vengeance M95 Performance MMO and RTS Laser Gaming mouse would definitely be on my short list of the top five contenders for my money.
