I have been using this laptop for 3 month now, here is my mini review:
-Keyboard is very good
-Screen is very good, colors are awesome, you may have to use the setting though as on mine I couldn't see properly dark video or shadows.
-Touchpad is very bad, not the worst I have seen but for that price it's a big let down, my old K 17" asus was better than. It's very bad, it often mess up my navigation tab on chrome, or it zoom randomly at 300%.
-There is coil whine on it, noticeable like it's a HDD but there is no HDD in mine as I put a SSD. Another let down for that price, my old K Asus didn't have coil whine. If you have a HDD you may not notice it though as it's exactly like a HDD noise.
-The laptop is very quiet for a gaming laptop, if it wasn't for the coil whine the silence would be perfect.
-Graphic card does his work, very good.
-Build quality is very good, very sturdy.
-There is enough usb port on either side for a 15", that's good.
Overall it's a very good laptop, if it wasn't for the bad touchpad and the coil whine it would be a perfect laptop for me.
