Easy.

Quite convenient

No Chinese service at pickup, making communication difficult, especially when dealing with accidents. There is Chinese service at dropoff, making it simpler.

Self-service pickup, spent a long time finding the car in the big lot at night. It was too dark to inspect the car.

I only used the car for one day and had to return early due to a family emergency. They showed no sympathy at all.

The car rental provided an international driver's license translation, but they didn't mention that the translation needed a photo attached. As a result, the car rental point did not recognize our driver's license translation! We ended up paying to get the translation done. It was frustrating and we waited over an hour at Queenstown Airport to get an authorized translation. Very unpleasant experience!!
