I bought the product just after its launch in September 2012 at a whooping 40K. Amazing quality overall, but you will miss the metal body if you are a iphone fan.
There have been issue with the battery charger, I have it replaced twice.Rest the phone is fun to use. The stylus part is useful only when you do things at micro level such as writing and stuff.
I have used it only 1% of the total time. You do not need a scratch guard as the screen comes with a gorilla glass and it is scratch resistant.
But the silver lining on the border is weak and it comes off very easily. Sometime handling becomes an issue, but still you can use it if it is within your convenience.
