I have used services of all courier companies and felt blue dart is one of the best. I have shipped an parcel on 19th december night at 7:00 pm from Chennai to Jaipur and to my surprise it was delivered on the next day at 12:00 Noon to Jaipur even with Normal Delivery instead of Priority Delivery charges.
So I would recommend this to everybody who want to send urgent parcels to areas where blue dart has the services. I believe most of the problem occurs because we ship the shipment to the area where blue dart does not have the services.
Let me clarify myself - I am not an employee of Blue Dart. I have not only experienced Blue Dart as customer but also blue dart as receiver of goods also from many online sites. (As I like to shop online for standard items) I was never disappointed barring one or two times.
As I can see anger from most of the posts, Its because generally satisfied persons do not write the reviews and I tried to do so. Anyways its individual to decide what they interpret from my review.
