The Corsair weighted mouse and keyboard works wonders as long as you are using the ICUE software. The mouse, sometimes will disconnect from the software and you can tell it due to it will start to become super sensitive and move really quickly but if you open the software and it is not there then simply plug it into the computer and it will connect.
The weighted mouse has weights on the bottom of it and you can take one out and adjust it to what you need. I actually lost one of my weights a few days after I got it like 3 years ago which is okay because you can buy weights for it.
The mouse is Bluetooth or dongle but it can also be wired if needed. I personally love mine. It is very useful in games since it has an aim button that makes it hard for you to move your mouse while shooting causing you to miss your shots.
My corsair keyboard, I personally love it since it has extra keys for me to key bind my software’s to making it way easier to start and stop my streams. I can personalize the colors and the patterns and make them go the way that I want them to.
Overall, in my opinion Corsair makes good products. My ram sticks are also Corsair and I have yet had a complaint about the company because everything pretty much handles everything I throw at it.
