Three weeks before I have booked it for my wife. Yes its not bad as compared with Redmi note 3 or other product. If we see camera than front camera does not have flash but back camera has that option and photo qualities are better than Redmi note 3.Since Redmi note 3 has 16 MP camera and Lenovo K6 Power has only 13 MP. Battery backup is good since it has 4000 mAh battery but it takes lots of time to charge. Thats not a big issue.
Product quality, hardware and display are good, phone also not so big that you cant carry . I have cancelled my decision to buy Redmi note 4 for my wife since I have already Redmi Note 3, and now I am feeling that my decision was not bad.
I am happy with it and my wife loves it.
If we compare with other phone on the market than Moto E4 plus was best option than Lenovo K 6 Power with same price. But I am happy with it. Since its much better than Redmi product.
Friends, if you want to buy it than must buy, dont go with Redmi.
