Generally very easy.

The counter staff refused to proceed with my order when picking up the car. After driving out of the lot, the personnel discovered the paperwork was under someone else's name, not mine. I waited over half an hour for them to redo the paperwork. If not for the diligence of the car lot staff, I would have given a zero rating. Additionally, my credit card was charged twice, each time $200. This is despite having paid the rental fee in advance while in my home country.

No wait for pickup. Booked a compact SUV, but received a mid-sized SUV instead. The exterior had several minor scratches, and the interior was quite dirty. Luckily, the car drove without issues and there were no complaints during return. Refund of the $200 deposit was processed within half an hour after returning the car. Note that getting the car earlier means you’ll need to return it earlier as well. Picked up the car within half an hour of landing on Kauai Island. Overall, satisfied.

The process was convenient, the car was in great condition! The service was excellent, no pressure to buy insurance. The staff were very friendly. Returning the car was especially convenient, Hertz's management was very efficient, they inspected the car on the spot, printed the receipt, and the deposit was refunded instantly.

Good

Very convenient. Initially, they only asked for the online order printout and then requested the return slip, but there was no need for a translated driver's license. The staff were very friendly. I mentioned that I needed a car with a USB port, and they patiently searched the system for several minutes to find one. The vehicle was brand new, having only driven about 300 miles. Picking up the car was also very convenient, right in the hotel's garage.
