I have owned my Acer E1-571 for almost 3 years now and have not had any issues with it at all. I use the laptop for accessing the internet and studying. For the price it is a good laptop, sure there are aspect of it that feel a bit cheap- the keyboard and mouse pad, but nothing shocking or enough to annoy when using. I have 8mb RAM and there has been no issues with running several programs at the same time. When I bought it the OS was windows 8 which took a bit of getting used to, I have since had windows 8.1 and now using 10.
All in a ll I am glad that I got this laptop. I think I was about £350 at the time. It has worked well for the past 34 months(still silent and no issues with heat, screen display or speed) and I think that it will still work well for a good while longer and ultimately end up being a bargain.
