I have purchased this for my personal use in sep 2014 for 2100 rs and yet few days back it stops working but then I aporoach to service centre and call them and explained my problem.
On the next day they send a service man to my home and he have replace the battrey so overall service of numeric is awsome and very fast as I raise complain at 8 pm and on the next day at 10 o clock the service man was at my home.
