The pick-up and return process was very smooth.

Incorrect pickup and return address.

1. Circula sends a representative to pick up customers at the airport holding a sign since they don't have a counter at the airport. This wasn't clearly indicated by Zuzuche, causing us to search frantically upon our late-night arrival. The representative was also waiting cluelessly with the sign. 2. Make sure to check the car pick-up and drop-off times carefully written in English by the rental company. We arrived late, exhausted and stressed, and thought showing the Zuzuche order was enough. They handed us an order, we signed it quickly, only wanting to get the car as soon as possible. We didn't realize they put the return time a day earlier. When it was time to return the car, the Circula owner scolded us, asking why they couldn't reach us on our Turkish phone the previous day. We found it weird because we had a data SIM card, not a phone SIM card. We had our Chinese phone, why didn't they contact that? They wanted to charge us an extra day. I urgently called Zuzuche, but it was 3 or 4 am in China, and although someone was on duty, they couldn't actively resolve the issue. After returning to China and going through some trouble, they finally didn't charge the extra day, but it was a waste of energy... really...

The service is very enthusiastic.

The first car we were given had a gas tank that leaked, so we had to change the car when this was discovered. When we discovered this problem it was difficult to get the car changed. We wasted one day waiting for the new to be delivered and had to keep contacting the company. The second car kept giving us a maintenance due message. Thankfully nothing went wrong. Staff members we dealt with face to face upon receiving both vehicles were pleasant.
