Really great product worth every penny. But please do not pay full MSRP.

The G700S is the first real gaming mouse I've purchased for myself. Aside from the sort of thing you could pick up for pennies on the dollar at any discount PC-wares website, this is the first. The real deal. The build quality and form fitting shape should be the first features you should notice aside from the sleek design and button-layout. It runs itself off of either any AA battery you can stick in it, the rechargeable AA that comes standard, or even by its USB cable specially made to form with the contours of the mouse. When it has powered on, the indication lights on the mouse will let you know the initial charge which is always nice with a wireless mouse so you're not reliant on software to let you know. It's fairly close to Plug-And-Play, but it only improves with the addition of custom G-Series software you can download from Logitech's site. This software will only make improvements on the G700S such as assigning custom mapping to the multiple keys, setting your DPI settings (which default can be changed with the G11 button located topside of the mouse), and creating profiles which change the settings of your mouse to better fit the needs of the games you play. The feel of the G700S mouse is close in resemblance to a friend's MX Revolution, but is a tad longer and thinner in overall form. The curvature is sublime in the best possible ways. But it is best made for average to smaller hands, in all honesty. With the button layout featuring 4 side buttons, you would expect it to get confusing/uncomfortable trying to use them in everyday use. But it becomes almost second nature after much use with the mouse. But just with any gaming mouse, you're going to want to keep this thing handy with any machine you use. You'll miss the familiar shape and the button layout, but it would require you to reinstall the G-Series software to get the most from the mouse as you would have on a normal basis. So this is more of a mouse to have if you have a single gaming rig and don't plan on changing that. Plus it is not quite the versatile, button-having monster you would require to get the most out of MMOs or games of such nature. This is more for the (for lack of a much better term) "casual" gamer who uses their free time to game rather than do it out of a professional purpose. And if you do it in a professional standing, then I guess it's best to call it a "Just the bare necessities" type of gaming mouse. Enough buttons to keep your more important actions at your fingers, but not enough to scare off anyone interested in coming to the PC gaming dimension as a diplomat. The bottom line is that this mouse is an (almost) perfect starting mouse. Biggest pros include its button count being enough to be useful without being scary or excessive, a nice comfortable feel since you're likely to use this for hours on end if you're anything like me, and its a fairly standard shaping so even if you part from it for an extended period of time you won't forget how to use it. But cons mostly concern its portability and price range considering I'm likely to never buy another mouse again for anything above what I can buy dinner for on even the most special of nights. This is an ambassador to PC Gaming mice for the commoner to seek to for a comforting arm. And if you can bare the pricing, I say it's worth scrounging through the press to get a quick word in and get you familiar with this new land. (Translation: eBay this sucker. No more than $40.)Read full review
