My comparison with redmi note 3 and some drawbacks I saw in lenovo are
IR blaster in redmi note3 but lenovo doesnt
4k video playable in redmi note3 but lenovo doesnt
Battery 3500mah where redmi note3 have 4100mah
Processor speed is good in redmi note3 compared with k5.
Notification LED light blinks only red & Blue in k5 but in redmi note 3 blinks all colors.
Downloading speed is good in redmi note3.
While using jio sim android.process.com pop up makes upset in k5.
And some good points in this k5 mobile are
Look Good
Fingerprint sensor is fast.
Front and back cam superb in Good lighting condition.
Macro photos rocks.
Screen sensitive is good.
Dolby audio rocks in both loudspeaker and through Earphones.
Just think a lot of it and go for 12k variant it worths the money. Hope my review is helpful.Have a nice day.
