Yep, the worst. They scratched my G20CB while replacing a motherboard (like they laid it down on sand to work on it) and it took over 3 times sending it back and forth to get repaired, each time it getting marked "nothing wrong" sent back the same way it came in. I too will never again buy Asus.
Asus G20CB - Core i7 6700, Nvidia GTX980, 16GB Ram, 256GB SK Hynix SSD, 1TB Samsung SSD.
