I seldom use any courier service. DTDC is a brand that I can rely on.
I have used the services provided by the Mira Road Branch, which is quite amazing. They are really quick in processing the order and delivering it.
The state of the courier by the time it reaches the destination is also good.
I had sent a book for my cousin in Dubai which had reached him 7 days however; people had informed me that it would reach the destination in some 10 days. I was really impressed. Also, the staff are quite helpful and prompt.
