I have Dell Inspiron 15R 7520 Laptop for a very long time, and I have very good experience with this product. Dell is always known about it’s rugged and rigid products. The customer service is very good, when we need any assistance on any of their products. I have few issues while using this laptop during my warranty period, which Dell associates solved at once by sending their customer service partner and I had to just drop an email to them.
All the specifications and features they mentioned when you buy the Dell laptop are all present and worked very accurately. My laptop has a wide 15 inch screen with a crisp display, 4GB of RAM works very well when it comes to multitasking and had a huge amount of storage space i.e. 500 GB. Dell Inspiron is a middle segment in their laptop series. At very low level they have Dell Vostro, then Inspiron and then Dell Latitude.
You can buy any of the Dell Laptop, they all look premium. And if you think the cheapest one cause problem at some time, the Dell after sale customer service is always their to help you.
