Pros: Good feel, well-placed grip intents and buttons, decent size. For someone like me that has large hands, it fits well into my grip, plus, it's well-contoured so it would probably work for someone with smaller hands too. The color scheme is as expected for "gaming" hardware, with subdued colors and matte black dominating, giving it an attractive look.
Cons: It's all hard plastic, with no rubberized surfaces to enhance grip. Also, this mouse replaced a failing MX518 and, while it does the job and superficially resembles that old, amazing piece of equipment, it just doesn't feel as solid. I hope this lasts as long as the old mouse did, but I'm not getting my hopes up.
Summary: for those who reviewed lower eggs coming from the MX518, swearing by the MX518, have fun with the anglesnapping problems!
Pros: Coming from someone who has owned the MX518 and 2 G400 (one with PID and one is S/N), the G400s is an improvement on something that was already great to begin with! From the G400, the wire is now reinforced, and the DPI has slightly been improved. I've had no problem with it since!
Summary: This is my first gaming mouse and I was a little ambivalent about spending $60 on a mouse but the g400s is totally worth it. Many mice advertise really high DPI settings like 8400 but the average gamer will probably never go over 2000 so before not to over pay for frivolous specs.
Pros: The design is amazing. Great feel in your hand and suitable for both palm and claw grips (I have average sized hands). Very smooth slide, nice weighting and the rubber on the side has just the right amount of grip.
Cons: None really, No buttons that can be programmed for in game skills/abilities but that's irrelevant for me.
Pros: I switch my mice between this and the Razer Naga. I use my almost broken and highly annoying Naga for MMOs. I use this G400s for FPS gaming. I highly recommend this mouse for all those heavy FPS gamers. The on the fly works great, software is easier to understand and use than the synapse I use for the Naga. Very well priced for the quality of the mouse.
Cons: The cord looks pretty cheap, but it hasn't broken or anything, it kind of worries me though. Also when I installed the software for the 1st time, it crashed my PC. I just rebooted, and everything was working fine. Also you will get some input lag with this mouse, but I use a mouse pad so I don't see it.
Pros: I decided to buy this mouse after my beloved Logitech MX518 broke, resorted to my old Deathadder, and that broke after a week. It was either this mouse or the Deathadder 2013, I'm glad I went with this mouse. Has the old shape of the MX518, with a higher DPI, nice feeling clicks for all those fast FPS clickers like me. Software with this mouse is really great, and is easy to understand for all those beginners on programming macros and shortcuts to your peripherals. On...
Cons: The cord on this mouse seems to be a little flimsy, it looks like it's about to snap off, but mine hasn't. Also if you don't have a somewhat good computer, you will get some input lag when you are playing. However for the amount of buttons and for the on the fly DPI and excellent software, you get what you pay for, at a very low price for a good mouse.
