Although I don't speak English, communication was smooth using a translation app.

Both pickup and return were at the airport. I saw long lines at other rental companies, but AVIS was very efficient.

Picking up and dropping off the car was very convenient.

Overall, I am satisfied. They didn't push extra insurance. Initially booked a GPS, but later rented a WiFi device in China and downloaded Google Maps in advance, so I didn't need the GPS anymore. They refunded it directly when picking up the car. Returning the car was also very quick!
