Logitech G703 Lightspeed Wireless Gaming Mouse, 12000 DPI, RGB, Lightweight, 6 Programmable Buttons, On-Board Memory, Long Battery Life, PC/Mac - BlackCarbon Neutral Certified by SCS Global Services

I've been using a G402 since 2014, but this year I decided to finally upgrade to wireless after dealing with cable drag for far too long. Note that this mouse is identical to the G403 save for the wireless connectivity.I'm very impressed with the build quality and ergonomics of this mouse, thought it is a bit shorter (front to back) than I would like. The shape is very similar to that of the G402, with a slightly higher ridge in the palm arch area and concave buttons instead of concave ones. if the G402 is comfortable to you, you'll likely find this mouse comfortable as well. The weight distribution is a bit different on the G703, with most of the weight focused at the back of the mouse near the optional added weight.One major difference between the G402 and the G703 is two fewer side buttons. Personally this is sort of a let-down, as 4 buttons and a dpi-shift button was a good balance for me. However, the two side buttons (down from 5) and one extra top button (dpi-shift) are much higher quality than the extra buttons on the G402, without the G402's sharp edges. Also notable is the lack of glossy black anywhere on the G703, when it was very prevalent in the G402's angular design. This is a pro for me, as that material collected fingerprints like mad, and the frequent divets in the G402 collected dog hair as well. The G703 is far smoother than the G402 but has some missing buttons that may be important to certain users.Let's talk about wireless. Wireless mice are tricky for gaming, and Logitech has the best wireless implementation that I've ever used. That being said, the input lag *is* noticeable, but definitely not unbearable. I don't play a lot of competitive games, so I may not have the finest-tuned eye for this sort of thing, but I got used to the feel of this mouse after about an hour of gaming with it, and I can really only detect the slight input lag (think 6ms instead of 1ms) when I'm actively looking for it.The battery life is good, but not exceptional. With the high polling rates, sensor quality, and absolutely necessary RGB lighting found on gaming mice, it's natural that the battery life would be lower than other Logitech wireless mice such as the Performance MX or MX Master. The battery lasts around 25 hours as claimed with the lighting on and in heavy use. Most people could probably go a week or so easily without charging, but I would plug it in to charge overnight at least every few days just to be on the safe side. One nice addition on the software side would be a tray indicator for the mouse's battery life, but I guess "the technology isn't there yet." (This whole paragraph is somewhat moot if you have a Powerplay, which I don't).I can't speak to the durability as I haven't had the mouse this long, but I've had a great experience with Logitech's customer service in the past with the 2-year warranty included with their product. I would recommend this mouse to anyone outside of the most hardcore latency-snobs with its comfortable design, pleasing aesthetics, and excellent wireless.

Honestly, I thought that was some sort of minor input lag when running it wireless. I previously owned a G502 and it grew onto me. That is until the weight of the G502 started causing problems for me. Running it at 400 dpi hurt my shoulder. However, I saw an advertisement of the G703 and I was fairly interested. I started to dislike wired mice because the braided cable could come off, leaving a stiff edge sticking out. I was always interested in wireless mice because of their convenience. But I was always concerned about the latency rate/response time on the wireless mice. Logitech claimed that the G703 had a response time of 1ms which seemed promising. A big name saying the mice response time nearly instant? Deal. I saw reviews on this mice and many people have said their cons which made me think back if it was worth buying the G703. I still bought the mouse and it easily exceeded my expectations. At 107g, it is definitely lighter than the G502 which was something I wanted. The texture of the mice is definitely nice.PROS/CONS:PROS:- Response feels smooth- Quick response- Texture is amazing as the sides provide more grip- Side buttons are easy to click- Left/Right click feel perfect- No issue in gaming- Much easier movement like freedom, than a wired mouse- Charges insanely fast- Fully charges within an hour- Wire is braided- Hooks on the micro usb plug (reinforcement)- RGB lighting is bright, love the RGB light on the scroll wheel- Easy to program- Relatively light (107g)- Pretty good battery life (Gamed for 14 hours straight at 100% *RGB on*, 60% left)CONS:- Middle mouse button (scroll key) is stiffer than preferred- Tips backward if you apply lots of pressure onto your gripping on the mouseAs you can see, way more PROS than CONS. To make it simple and short, it's worth your money. This mouse is extremely underrated in the ranking charts.

Amazingly good.I use this mouse primarily for office work. Tried multiple mice from Microsoft and Logitech, the rest (except G603) have various issues so I had to keep trying. This one fits my hand perfectly, no fatigue from everyday use for many hours. The build quality is amazing. The surface is nice to touch; the sides feel slightly rubbery but not tacky, which results in confident grip. The mouse lasts for a week on a single charge, but can use it wired while it's charging. All buttons, primary and secondary feel solid and are comfortable. The provided USB cable is very high quality: very soft, bends easily (unlike one supplied with G603).Logitech software allows for easy customization of buttons. Once customized, the configuration is stored in the mouse and you can use it with another computer without installing the additional Logitech software.As an example of customization, I reconfigured the buttons as follows: the forward side button to a lower mouse speed to help with precise positioning when editing charts and diagrams, the back side button to cycle the mouse speed, and the top button to close a window.Not perfect (minor things):The middle (wheel) click is a bit tough; I use it primarily in web browsers for closing tabs and opening links in a new tab.The wheel is clicky and doesn't support "free wheeling".The wheel doesn't support left/right buttons on it (e.g. for horizontal scrolling).When connected via a USB hub, the Logitech software may not recognize it. It still works perfectly, as all profile settings are stored in the mouse.
