"No lag...Love it...On the laptops the mouse was smooth and fast....Feel: For a wireless mouse of this price point I would have expected the plastics to be brushed or feel a little more lux than they do, but it has a standard issue mouse feel The optional weight gives it some heft which is nice, and without it it's VERY easy to almost send skittering across your desk."
At this point, the major mouse makers' software packages have been through generations of refinement, so they are slick. Logitech Gaming System (LGS), Corsair Utility Engine (CUE), and Razer Synapse are three of the best-regarded mouse- and keyboard-control utilities that cater to gamers. All offer advanced tweakability, with CUE regarded by many users and reviewers as the deepest, but also the trickiest to master in-depth.
The mouse is a bit longer than most, but smaller than many of the 'ergonomic' mice. It fits my larger hands comfortably which many smaller mice don't. My wife has smaller hands and finds it comfortable to use. I have several young children and they have no problems with it either. the mouse is pleasantly symmetrical, and while nice to look at and fit in smaller pockets, my hand is not symmetrical.

Last but not least, if you're a professional gamer looking to buy a gaming laptop that can keep you competitive, be prepared to brown-bag your lunches for a while. That kind of high-end performance can only come from top-of-the-line components, especially in a portable package, and they don't come cheap. Plus, an emerging trend among high-end machines is a high-refresh-rate screen built into the laptop, which allows for display of lofty frame rates in full to smooth out the perceived gameplay. Note, though, that you'll need a powerful graphics chip to leverage the benefits of a high-refresh panel with demanding games. You'll be able to identify machines like these by marketing lingo touting, say, a 120Hz or 144Hz screen. (A typical display on a laptop is a 60Hz panel.)
The battery life of most gaming laptops should be ok when you arent gaming. I'm sure most of us understand this. For people who want to play games but also need a laptop for work or school, the batteries should last long enough. I'm assuming most if not all of them are set up so you can run them off the intagrated graphics until you need the dedicated for gaming or whatever.
