I recently bought a Micromax A110Q, the set after opening from a packed piece was defective; had to suffer for its replacement from service center. After that the replacement was procured with great difficulty, however within a weeks time of use, the back cover started cracking up from the point of it’s mark to pull open. The plastic cover at it’s back is so fragile and of poor quality. I wonder if would be able to use it in the long run with bad experience in very beginning with this set.
