If your looking for a wireless mouse without spending $70 or more and want some versatility as well, I would definitely recommend the Logitech G602 Gaming Mouse. It's a very comfortable, user-friendly and reliable mouse with its 11 programmable buttons.
I feel like 2500 is more than most people need unless you have a 4K monitor where the mouse would need to travel great distances. Buttons feel great, but the scroll wheel feels a little rough when you spin it, not a deal breaker by any means, just something to get used to when compared to other mice I've used. I use a fingertip grip and like to rest my palm on the table when I play games, so to me, the mouse feels a bit large.
Now on to the feel of the mouse. It feels great. Super comfortable and with the rough texture around the base, picking it up is super easy, even with the weight of both batteries making it a slightly heavier mouse. I use a fingertip grip and like to rest my palm on the table when I play games, so to me, the mouse feels a bit large. But if your palm hugs the mouse like a lot of people, this size would probably work for you. If not, it's something you might be able to get used to given the rest of the features this mouse has for the price. The buttons are also very easy to feel without looking at them. The only buttons I don't use often are the two closest to the wrist on the thumb buttons. The rest are a joy to use.
Not only is it good for gaming, but you can assign office hotkeys to it with the Logitech software making it a very versatile mouse. Even gaming on the endurance mode I haven't noticed any kind of input lag or jitters with the cursor. The mouse comes out of the box with 5 DPI setting you can switch to, but I usually stick with the middle 1000 or 1500, even in gaming. The fact that you can take one battery out to lower the weight a little bit is a really cool feature. When the battery is running low so it doesn't die in the middle of a game, and the software will let you know.
I have this mouse. I love it. I write this after switching to the G602 from a wired G500. I was worried about the weight, responsiveness and constant battery charging, but Logitech nailed all three.
If you're looking for specs, read the product description and marketing material. This review is purely my experience as an enthusiast user.
* World-class battery life (**I've tested 160 hours on a single battery**)
* Wireless works!
* Good build quality
* Textured grip on both sides
* Weight: If you run one battery, lighter than G700s, comparable to Naga Epic / Mamba
* Six thumb buttons, just enough to feel pampered
* No accidental thumb button presses
* Top three thumb buttons are high, slightly reduces control
What I miss from my G500:
* Free-scroll / hyper-scroll
* Lighter weight
Fine build quality. Textured grip as on other Logitech mice, with a rather short thumb rest. Mouse moves around smoothly on its pads.
Mousewheel is tactile but quiet. I still sometimes run into issues where the trigger-point for the mouse-wheel click gets off-center, but it eventually jiggers itself back into place. I encounter this with plenty of other mice as well, so this is not an explicit negative. Just like how omitting my beloved free-scroll is not a full negative either.
Wireless works fine, though you may need a line of sight to the receiver. It includes a USB extender.
Love the thumb buttons. They're right above where your thumb rests (easy access, no accidental tripping with a tight grip). The top three buttons are a higher than you'd expect, but I got used to it. The thumb buttons have rather pointy edges that dig into your fingers and need a reasonable amount of force to press. This actually increases the control you have with your thumb on the buttons.
I like that because I can distinctly feel the buttons and there is no chance of accidental clicking, but it may be uncomfortable for some people or difficult to access/trigger while whipping the mouse around.
Very useful having two sets of three buttons. Mine are set up like this:
Back – Middle Click (open in a new tab) – Forward
Previous Tab – Close Tab (Ctrl-W) – Next tab
As much as I like using Vimium for no-mouse browsing, this allows super-fluid one-handed browsing. I need not explain why this is a benefit. You'll understand when you grow up.
Battery life is phenomenal. It lets you run with only one AA battery for reduced weight, which is my preference coming from a wired G500. I got used to the weight, but still, run one battery because…
My experience with the Logitech G602 Gaming Mouse, one plain battery, performance mode, **lasted 45 days**. (It gives you a 5% warning on your computer and lasted 3 days past that.) Estimating a conservative 25 hours a week, that's **over 160 hours of use from a single battery**.
You can get much better numbers by inserting two batteries, using a high-capacity Eneloop and switching to endurance mode, but I am perfectly okay switching out a single battery every 1.5 months. When the low battery alert surprises you that your mouse even has a battery that needs swapping, charge time is a non-issue.
