Remember to bring a printed translation document when picking up the car. I've rented multiple times before without using a translation document, and thought it would be fine this time as well. However, it turned out to be quite challenging to communicate, and in the end, I could only rent the car using my passport and driver's license.

Pickup and return were very convenient, but if the car encounters issues during use, it can take up a lot of time and effort. The car couldn't be opened, and I thought the key might be out of battery. Hertz didn't have batteries at the store, so I had to take a taxi to buy them myself, but changing the battery didn't solve the problem. Eventually, I had to wait for a tow truck to take the car away and then take another taxi to the Hertz store to get a replacement car.

Couldn't get the desired model, the car's power was insufficient.

There weren't many people in line, only two in front of me, but the two staff members at the counter were extremely slow. Each transaction took too much time.

The service was okay, but since it was my first time driving in the USA and I was unfamiliar with gas prices and how to refuel in the US, I didn’t choose to return the car with a full tank. From San Francisco Airport to St. Louis Airport is less than 400 kilometers, and according to the car type provided, we only used about 70% of a tank, but the rental company charged us $57.52 for fuel. At that time, this amount could fill more than two tanks. I raised this issue with the car rental customer service, but they said they couldn't handle it. In fact, it’s very easy to return the car with a full tank at U.S. airports. This is a reminder to other customers to avoid unfair charges.
