I am using a Dell inspiron 15 3000 series laptop from the last 15 months. The built quality of this laptop is very poor. Screen resolutions are not as much vibrant as present in laptops of other brands. Performance was great in starting but from the past few months I am having some lagginess during surfing on multiple windows on Internet or working with multiple files and heavy applications. Battery backup is good enough and stands for 4 to 5 hours of continuous usage.
Overall this inspiron 15 3000 series is a very average laptop series from Dell and if you are planning to buy it then keep in mind that don't expect so much from this product.
