Atrocious customer service. Far and away the worst I have personally experienced, and also heard others experience. Unfortunately, out of all 4 or 5 people I know who have used a Micromax product, everyone except one has had their devices fail. So, unreliability, check 1, but worse still, the horrific after sales support.
Personally, in my case, I picked a Funbook Pro just to check it out - after all the value for money seemed very good on paper, like all MMX products. I barely used it, but as I anticipated it died. The "service checkpoint" was a rather pedestrian facility and the staff was extremely rude, but that is OK, motto of Indian customer service "customers are paupers, not kings". But it went downhill from there. They told me it would take 15 days to repair, which is beyond absurd. Fine, I gave it up as I use another tablet, and the repair was free? Oh wait. After a week, as it turns out, they randomly decided that a certain part was not covered by warranty and decided to charge 35% price of the entire unit. My first instinct was "trash that shit" but I let my poorer judgment win and went in for it. Surely everything should be fine now. I got the tablet back after some 14 days (at least they are aware of their inefficiencies...) to find that they forgot to connect the battery back. By this time I had had enough, and decided to get rid of it, thought maybe someone from TE would take it up with MMX service if I gave it away for half price. It seems no one is interested, and I don't blame them. So finally, it is time to send the Micromax product to where it belongs - the trash bin.
Of course, it goes without saying that you may be lucky and get solid service, but is it worth the risk? I seriously doubt it. If you are severely cash strapped, I recommend not being greedy about specs on paper and get a solid product with guaranteed performance, like a Lumia 520.
PS: I don't have any experience with Canvas 2. Maybe you will have better luck. But who knows? Is it worth the adventure?
