hello friend, 
i want to buy one of hyper x mouses and use it in apex
which hyperx mouse you use, Pulsefire Core, Pulsefire FPS,Pulsefire FPS Pro, Pulsefire Surge ?
Thank you, 
I have a Pulsefire Raid and it works with XIM4 and Apex. It’s not my main mouse but I use it for games that need extra buttons because the Raid has 5 side buttons.
I also have a Pulsefire FPS Pro that I won in a contest and it’s very high quality. Solid build, excellent scroll wheel and clicks, and a top sensor. Trying the FPS Pro is actually what made me buy the Raid and I was happy to find that it has the same great characteristics.
My only suggestion for these mice is to swap the cable and feet. The OEM cable is too stiff for my taste and the feet are a little slow. I’ve installed paracorded cables and Corepad Skatez on both of mine and that solved the issues.
