Summary: There's very little not to like about this 15-inch Asus ROG Strix GL504GM. The build, the keyboard/touchpad, the display, the speakers, the hardware and especially the way this device performs in everyday use and with games are among the best you can find in a mid-range full-size laptop. But there are still some quirks you'll have to accept, as well as the fact that this computer is more expensive than most other alternatives with similar traits.
