The Union Square location was somewhat busy. We operated the machine, but after resolving everything, we still waited half an hour to get our car. Overall, it's acceptable.

1. As soon as I said I didn't need their insurance, their attitude became very impatient; the difference in attitude was too big. 2. I started the pick-up process at 8:45 but didn't get the car until 9:30, though my reservation was for 9:00. 3. Although I prepaid, the reserved car model was not available. Initially, they said it was being washed, but after half an hour, they said there was no car available and could only upgrade us to an oversized SUV (a model not found in China), which was very difficult to drive. However, the manager who upgraded us was Chinese and had a decent attitude.

Remember to bring an international driving permit when renting a car; without it, the rental location might refuse to rent to you. It might be possible at the airport. QEEQ's customer service said the permit needs to be mailed, but you can actually do it online and just print it out.

There was an issue during the rental process. The website stated that a translated document could be used, but the store required the use of Alamo's translation software. I had to go across the street to print it, costing me more than 3 dollars and wasting over an hour. Other than that, everything went smoothly. The car was a Buick Enclave, but the air conditioning was somewhat lacking.

The car pickup point at Union Square, San Francisco, likely due to its proximity to the city center, has very enthusiastic staff, but the queues are extremely long. There are self-service pickup machines nearby, but due to operational issues, their efficiency is very low.
