I needed a new wireless, ergonomic mouse used for normal use and gaming. I am huge gamer, who mainly games on PC and this mouse rung all the bells and whistles. Great Battery life, can last a very long time before it needs to be charged. I also love the added case with the weights in the mouse, it is good for long gaming sessions and the weight also improves the mouse's travel speed and surface friction. these weights add a small amount of heaviness which is ideal for first person shooter games. the only downside is that it uses Micro-USB instead of the more, modern USB Type-C connection. due to it's lightspeed technology there is very little latency and performs better than expected. it is a bit expensive but, worth every penny.I also like how the mouse goes into deep sleep when inactive for a time period to conserve power and save battery. the mouse is controlled using Logitech's G Hub Software, while not perfect it offers enough functionality to customise your mouse. which is available on Windows and Mac. the mouse also works perfectly in Linux albeit it needs some tinkering. you need an opensource app called piper which acts a frontend to libratbag which is the driver that controls the mouse. if you want to know the battery, you need to download another software called Solaar which are both available in pretty much any repo. only downside is there is no software on linux that can control the rgb properly, you can use Ckb Next or openrgb. but both are not perfect and will not always work. hopefully, Logitech adds support to Linux or the Open Source community builds a software that is similar to Logitech G Hub which can control the lighting, the core support is there. All in all it is a great mouse and works as intended.
