Hey, I am going to give you some good and some bad review for Lenovo k6 Power. I am using this phone from 3rd of February this month. Sound quality is awesome on handset. but when I connect my head set then the sound quality has drooped. Over all sound is very good. It is easy to use with single hand. Just 5 inch screen including 3 GB RAM. It is very stylist phone and very slim design. I face a problem the there is no light in bottom panel. There is a huge features range in this phone. good phone good reliability and Durability. I think in this price range it is a very good phone, everybody should use this phone.
