I used if for a year. The phone is good with cyanogen OS which offers customisation. The Yu forums have good development so you can try Custom Roms and kernels to increase performance and features.
Camera is average for 13mp range.
Heating is present while gaming and 3G/4G
Battery is Average for Heavy internet user like me.
You will get around 5.5 hrs backup on cintinous usage.
The display is sharp and good.
You can claim service at nearest Micromax center.
