I bought Dell Inspiron 15 R around 9 months back. Till date I have not encountered any issue.
I am very happy with the processing speed as it has for a core i5 processor and 6 GB RAM. The laptop is sturdy and reliable - synonymous to other Dell products.
I have also been using Skype regularly to connect with my friends and family located outside my country and I am very satisfied with the performance mainly on account of higher screen resolution
If anyone is looking to buy a laptop in the range of 30-40 K, I strongly recommend them to consider this product.
