I LOVE IT! Been using it for a few years now. I fly using the stick on it for collective and rudder, the rest of the buttons I use for stuff like countermeasures, NVGs, all the PTTs, inventory and all the normal keybinds. The beauty is it has four "pages" where you can swap to a diffewrent set of keybinds on the fly. So, if I am on the ground I use the first page, if I sit in as pilot pg2, if I am co-pilot using the camera/weapons I have another set up and that leaves one whole page for radio channels. I never have to touch my keyboard while flying. Just G13 and mouse. I also have a HOTAS but I just can't for the life of me fly rotary with it. I mostly use that for Elite Dangerous and DCS.
If you can find one good price, it's well worth the G13 for many games.
