I was looking for a wireless gaming mouse ever since my last one broke and saw this one was on sale. I had my eye on this one for a while after reading that it had negligible latency (around 3ms) which is important for most gamers. After using it for a solid week, I can say that I haven't had any performance problems. You can download logitech software for the mouse that lets you control it's settings. Just google the name of the mouse and it shouldn't be hard to find. The program is pretty intuitive. It took me only a minute or two to figure out how to use it. It lets you change the LED colors, the DPI settings, the polling rate, etc. It also tells you how much battery life the mouse has. The max is 24 hours, though I haven't tested it to see if that's true. Charging it is pretty straightforward too. Just plug the cable into a USB port and into the mouse. I normally use it plugged in unless I'm traveling or gaming. As for the mouse shape, I would say it's pretty good. It fits my hand reasonably well and I would say my hands are around average for a guy. The hump might be a little higher than a lot of other mice, so if you prefer a flatter mouse or have small hands, I would steer away from this one. The only times I wouldn't recommend this mouse are if you have trouble with mid-sized mice or if you need a battery that lasts longer than 48 hours. But if you're looking for a wireless gaming mouse, I would definitely recommend this one.

Wow this Logitech G403 is fantastic. I have a Razer Mamba Chroma Wireless (a much more expensive mouse) and I consider this so be a better gaming mouse. There's virtually zero lag that I can feel and the battery life is much longer than the Mamba Chroma. I have played over 1000 hours of Overwatch and my wrist would get fatigue from my Razer Mamba, that is not the case with the G403. The only negative thing I can say about the G403 is that I would like to see a charging base.

What a terrific mouse. Great size and shape (similar to Deathadder from Razer but just a little bit smaller) coupled with terrific switches and sensor. Along with the wireless portion of this it makes a truly terrific mouse that lasted me 2-3 days of heavy use before needing a recharge. My only problem with the mouse was a simply awful scroll wheel that was rattling every time I moved the mouse and was much harder to press compared to other mice I've used. Overall, I deduct one star simply based off my personal experience and I could have very well have just had a faulty unit in regards to my problems with the mouse wheel. Definitely would recommend this to anyone wanting an FPS mouse!

Amazing mouse! I've been using the Deathadder Chroma for a while already before I got the G403. It feels more solid than the DA and it's wireless! It feels great in the hands, and holds a charge for upto 35 hrs. I love the lighting modes, as well. In addition, the customer service at the Downey branch was great too. Even thought there was a huge crowd, they moved through the customers with ease and confidence.

Picked this up for $40 on sale . Works great . Holds a charge for a very decent amount of time and still works good when plugged in . Very responsive and comfortable . Exactly the same as the new model minus the witless mouse charging which isn't worth the premium price .
