It is a lot more comfortable than my G9x. Bigger, more buttons, that I don't use anyway. And wireless, now I'll have to mess with recharging it again. Best buy didn't have any wired that I was happy with. Wireless in the past has always been a hassle for me, either they would die when you needed them or the battery got weak and wouldn't hold a charge. Anyway seeing as the G9x is a good but smaller mouse, I was having cramps in my pinky knuckle from the way I had to hold it at long gaming sessions. This G700s reminds me of my older logitechs  in style. The dpi switches for up and down sensitivity are more conveniently located so you won't keep hitting them by accident. Which I had to turn them off on my G9x. But we will see how great this mouse is after 6 months. I hate expensive mice that die around a year of use.

From my own personal experience I can tell you I am perfectly happy with this mouse.  I loved the size and fit of the G5 series mice and this one is just about the same.  It tracks great, buttons all work great, and you can move it in and out of wireless mode very easily.  I've had my G700 since may 2012 and it hasn't let me down once.  Your G700s there should work just as well for you.

I think I just found my next gaming mouse. I have a G7 that I've had for years and its been great, but I like the looks and function of this one.
Thanks

Get yourself a cyborg rat 7(wired) or 9(wireless) which comes with two batterys. Game on
