The laptop is good and the screen is beautiful, but the price is a bit high for a 99% like-new machine. The battery life is decent but tends to drain quite quickly.

The machine works great, everyone. The like-new condition looks brand new. The Core i7 runs smoothly, and the anti-glare screen prevents eye strain. Definitely worth buying.
