Logitech G604 LIGHTSPEED Wireless Gaming Mouse, HERO 25K Sensor, 25,600 DPI, 15 Programmable Controls, Up to 240-Hour Battery Life, Dual Wireless Connectivity Modes, PC/Mac - Black

Pros:1. Good build quality2. Quick switching between modes (Bluetooth to 2.4, vice versa, useful if you want to connect to two PCs)3. Lots of programable buttons which is especially useful for games that use a lot of key-combos.4. Sleep mode if the mouse doesn't move for a while, which is useful if you forget to switch it off. I turned off the mouse maybe 3 times? and I have been using it for a month or so and the GHub app shows that my battery is full (4/4 bars).5. Mouse feet are of good quality, they don't scrape the mouse mat surface.6. Being able to swap batteries is a great touch, meaning battery degradation is non-existent.7. The back of the mouse stores the receiver and the battery, and is held by strong, but not too strong magnets.Cons(?):1. Mouse is relatively heavy, not too much of an issue for me, it can be for others.2. The scroll wheel is the loudest I have ever heard, but I wear headphones so it does not bother me.3. Rest space for the pinky would be nice.4. Albeit minor, the left and right click don't stay perfectly flush with the main body of the mouse.5. No third connectivity option, such as a USB Type-C, so if the Bluetooth and receiver break, your will need to fix it or replace the mouse.6. No RGB. I really don't care as it will reduce the battery life, but others may want RGB.

I have tried A LOT of mice this year, hunting for the best one. I don't play many games but I was looking for a comfortable mouse for work with extra buttons, infinite scroll, side scroll etc, and this is the one.I did try the MX Master but found it a bit uncomfortable. It may just be me but my hand kept getting caught on the right underside of the mouse. Everything else about it was great but it wasn't for me.This mouse on the other hand is a joy to use. It has a good weight to it, has 6 fully customisable side buttons that i've already personalised for my work use, and the infinite scroll works well (tip: adjust your scroll on windows to scroll 1 line at a time for a smoother experience). I only use the infinite scroll now. The ratchet scroll is fine, but a bit on the noisy side for me to use in a quiet office.It takes a single AA battery which, while not so good for the environment, it does mean you don't have to worry about charging it, and the battery life is great!As I said I haven't tested this for gaming, so can't comment on the refresh rate, compatability etc, but this is definitely a recommended mouse for productivity.

Well known bug of Logitech mice are the microswitches used, that are quite light, sensitive and prone to double-clicking with time. Temporary semi-solution is to blow inside the mouse to remove build-up of static but it only gets worse until the mouse will multi-click and stop dragging. At this point you'll have to either replace the mouse or the switches (tricky soldering).Other than this the mouse is great, has decent software, programmable buttons, runs on Mac (looking at you Razer!), good ergonomics, the battery lasts a long time. The ability to switch connectivity modes with a dedicated single button is also a nice feature. Shame on those switches.

This mouse is extremely comfortable. It did take my hand about a week to fully adjust to the size. The scroll wheel is weighty and has a free scroll mode which I love. The buttons on the mouse are very clicky and while abundant, they aren't intrusive. Even the side ones, the large thumb rest helps with this a lot as you can move you thumb away from the buttons.The mouse came with a battery which was great, and it's lasted forever! I have used it nonstop since receiving it and it's still going. The dongle is stored inside the mouse in a little covering, the same place where the battery goes, so it's easy to take with you.I bought this mouse for my Linux devices. This meant I didn't have to use the crappy software that LG force on you. I used a tool called Piper to control and bind the buttons on the mouse for desktop use, and configure DPI.It's great for playing games, they're all buttery smooth with no microstutter like with my previous mouse. Both of my devices I tested with had great responsiveness with the mouse. Completely recommend.

Nice mouse, expensive but worth it. The app is extremely useful. I've yet to use every button I only use 3. Every single button can be intercepted and remapped for individual apps, even the DPI buttons and all can be turned into marco's. Hyperscroll is extremely useful for web and for scrolling through thousands of lines of code - it will turn for roughly 12 seconds.Battery life seems great, 10+ hours a day for 3 weeks and battery hasn't budged. The only thing is there doesn't seem to be a notification for battery, you have to go to the app to see the bars. Not much of a big deal if the battery lasts for a long time but it would be good to know when to buy a new battery without having to open the app.EDIT: I got roughly 2 months out of the battery provided. The dead battery caught me off gaurd and I had to search for a battery, when I checked the bars on the app there was none I got another 4 days out of the battery. Would be a nice improvment if the app notifyied you about a battery so there would be as little downtime as possible if you have to locate a new battery. Not a deal breaker though.
