I purchased a Micromax Tablet from Reliance Digital and within 25 days the charger stopped functioning. I had to take it to the one service centre in the whole of Hyderabad where there were a sea of people. After thirty minutes when I managed to speak to some one they told me the charger would be replaced in a weeks time as they did not have the spare. The spare would be shipped from Delhi. I got the charger in 10 days time. The power back up is good for 30-45 minutes only. Not a good buy.
