So i recently purchased a glorious model o wireless and i have weird issues with it . I bought this as an upgrade from the glorious model d wired . I really liked the firekey option on the model d but that is not present on the model o wireless . The alternative is a macro that does the same thing , but that has problems . Like if i hit it by accident my mouse button stays in a hold possition (not irl just in games) and it confuses me why would it do that. I also have a problem with the firmware it says i need to have it wired and at the same time to have the reciever plugged in and it still fails. The support told me to install to CORE 2.1 but that software is full of bugs , the macro not working at all.
