Well this is a indian set with china parts. I bought this mobile in much high price because in 9000 price segment lot of sets were available with lot more enhanced features.
features- it has 1 gb ram 8 mp back camera and 2 front, quad core 1.3 processor, 8gb rom and the best feature is 5000 mah battery
the only best thing about this set is the battery backup it lasts for 3 days on heavy usage and 6 days if only call facility is used.
advantages are-the best sound speakers better than sony, samsung or iphone.the phone does not hang even with 1 gb ram and the build is stylish and strong.it will not break with frequent falls
disadvantages are that its a 3g phone with only 1 gb ram and internal storage if 8 gb out of which you get only 5GB is very less for apps you have only 1.5 gb so if you want to install more apps it will say more space needed.
go for this set if you have to experience the battery satisfaction.
