Very good

Very convenient, and the service is very good.

We had to wait quite a bit for the shuttle bus at LAX. Several AVIS and HERTZ shuttles came before one Dollar shuttle arrived. At the rental location, there were many people at Dollar, possibly because it was around noon, a peak time. We waited in line for nearly an hour. They did offer additional insurance, which is optional depending on your choice. Initially, we chose a Jeep Cherokee, but it struggled with uphill roads. Later, at the Dollar rental spot at San Francisco Airport, we switched to a GMC. Its performance was much better, although it consumed more fuel. The car exchange process was very convenient: just refuel, a quick inspection, and then you get a few cars to choose from, which was nice.

Not bad, the procedures were simple, and the car pickup and return were relatively quick.

Very good and convenient. As soon as we got off the plane, there was a shuttle with Dollar printed on it. The driver didn't even ask and just helped us load our luggage. When we arrived at the rental location, the service staff almost charged us for additional insurance, but thanks to the printout from Zuzuche, we avoided that extra charge. However, they still charged me for a tank of gas (as I originally booked full-to-full). This turned out to be convenient since I could return the car with an empty tank, avoiding any hassle. Overall, the price difference wasn't significant. In summary, it was very cheap, very convenient, and very valuable.
