I bought this Laptop Acer Aspire E15 ES1 - 571 ten months ago. I had a bad experience with this laptop. It becomes hang most of the time. Takes time to open a folder or any softwares. It has a 4 GB Ram and still its having hang. I have another HP laptop which I bought on 2009 and still using it has 1 GB Ram and works better than this. For Acer Aspire E15 ES1 571 the battery backup is very less. First 3 or 4 months it had battery backup and after 3 or 4 months it reduces now am getting about 1/2 or 3/4 hours of back up and most of my friends told acer product batter backup becomes less after few months. Its just not only my experience most of thems are. I wish the company could updates these defaults.
Thank you
