I have purchased K6 from flipkart via flash sale.I have to say this is the most perfectly balanced phone in the 10k price range.Metal body, sleek looks, fingerprint sensor, Full HD display, the usual lenovo UI which is cool, dual sim 4g, no lags no hangs and a long lasting battery which charges zero to 100% in about 2 hours 25 minutes.This phone is a flagship killer.All the right mix of features.But price could have been 500 less. Only competition for k6 is redmi 3s and Asus Zenfone Max but K6 wins on the Full HD display.Lenovo beats redmi in terms of service and support too.Azus Zenfone Max has a very long charging time so the winner in the 10k range is Lenovo K6 Power.The only cons is the combo sim tray which is annoying if you have to use both sims and a memory card at the same time.
