I am using this mobile micromax A106 Unite 2 and its quite impressive.This mobile comes with 1GB RAM and comes with 4GB and 8GB ROM.Processor is also good.its good for playing medium graphic games but not for playing high graphic games.720p videos plays smoothly and 1080p videos lags sometimes.the battery backup is quite good with data is kept off.battery drains faster while playing games and browsing internet.
so finally if you want to buy this mobile go for it.
thank you.
