It's okay.

Pick-up process was convenient, staff attitude was good. However, I rented a BMW X3 but was provided with a Mercedes GLC300de. The vehicle was relatively new, with less than 10,000 kilometers on the odometer, but the trunk was quite small, only able to fit three small suitcases. The return process was swift; the inspection staff simply walked around the vehicle and said everything was fine, and the deposit was refunded within an hour. A reminder for everyone: Swiss roads can be quite tricky. They are narrow, have sharp bends, and drivers tend to go fast and aggressively. There are many speed limits, restrictions, and mobile cameras enforcing them, with frequent incidents of concealed enforcement. Self-driving tours may not be very friendly here. Road restrictions change quickly and often, so it's crucial to drive carefully.

Very good, the reminders on the app are very thorough

Overall, it's acceptable.
