Experience flying on Indigo Airlines?

Hi there! Not sure if this is the best place to ask. But I'm planning a trip from Malaysia to Chennai and it so happens that Indigo Airlines has the cheapest fare so far. However, since I've never flown Indigo, would like to know if it's any good. A bit worried also because it is a lot cheaper than local Airlines i.e. Malaysian Airlines/AirAsia.

Would love any input/recommendations on flights. TIA!
