Works great in some situations and regions as in larger cities;
From Delhi airport hasn't worked well the last few times;
É common drivers do not know how to use a map and we have to help them find us or even find them;
Request a race location with good reference point (name of famous store, corner, temple, monument, museum, etc) can help a lot as well as, if necessary, ask an Indian from a nearby trade, police, etc, help by calling the driver;
Sometimes they decide not to come (just like taxi and tuctuc drivers do not accept to make the race to the place where we are going) and we see that the car stops on the application map. Sometimes this happens due to lack of internet, for example on the driver's cell phone (often very simple with limited antenna), it's worth waiting a while, otherwise the application starts charging for cancellations;
I always pay a good amount more because it is very little.
I often request the Prime mode (car a little less poorly maintained than the smaller ones), just as cheap;
