With its positives being: Everything is wonderful, but there is one caveat, which I will explain in more detail below. Below are some downsides: Phantom keystrokes are generated by faulty software, and the only way to get rid of them is to totally reset the keyboard data and remove the profile in Armory Crate. However, even after doing that, it's still easier to just switch off the keys that are causing the problem. This issue is quite frequent among purchasers, and currently I'm waiting for the firmware update that, in principle at least, should fix the issue.
