Gaming mice with many buttons are becoming more mainstream. Given their popularity, you probably won't be surprised to learn that updated versions of previously released products are being brought onto the market, as is the case for the Logitech G700s and the Corsair M95 gaming mice. Previously outfitted with a 5700 DPI sensor, they now both sport a new 8200 DPI one. We went looking for differences.
We would have liked to publish this review at an earlier point in time, but a problem with the Corsair M95 mouse forced us to wait for a firmware update. When we used the default firmware (version 2.16), there was a substantial delay between mouse and cursor movements. This problem has been fixed in firmware version 2.24. We therefore strongly recommend you perform a firmware upgrade if you happen to own this mouse.
Both products have many buttons: the Logitech G700s has 13, whereas the Corsair M95 has 15. Their prices are fairly close as well, averaging 99 and 86 euros, respectively. The G700s' slightly higher price gets you wireless functionality as well as a more extensive scroll wheel. Wireless operation is handled by a nano receiver, although you can circumvent this using a micro-USB cable. Both mice come equipped with the Avago ADNS-9800 sensor, although we're not entirely certain in the G700s' case, as Logitech does not publicly disclose such specifications. We do know that they don't just plug in a sensor off-the-shelf, but typically optimize them for their mice instead.
