Slow and outdated. AMD's Carrizo platform has not aged well. Performance is slower than a U-class Intel processor while offering shorter battery life and an overall poorer experience.

I am currently fighting Asus and the good quality of their products. Twice in 10 months the laptop was sent back, i am still without a computer. they keep finding excuses etc. if you by one make sure you get used to have a laptop that turns on in the middle of the night, opens in bios, the sounds mutes without reason you take the earphones off and no sound until you restart the computer etc.
If you want to put the money in the trash make yourself a favor and do not bother going to the store, just do it at home the result is the same.
