Terrible! Do not recommend. My ride should've been ~20 min. About 5 min in, it quit working. Idk why. There's no way to see your trip before going, so if I went through a restricted area,I had no way of knowing that would've been a problem before starting. Also, I wasn't even "rolling" the scooter, but actively had to push against resistance in the tires to make it move. For 45 minutes until I got to a parking spot. I don't even have a way to request a refund because their chat is broken.

I used the app in Vienna. Everything was fine- I bought a pass, I used it once. But then the map in the app malfunctioned. It shows only a blue screen, and doesn't show any scooter locations. I cleared cache, data, uninstalled/reinstalled... nothing works. So I can't use the remainder of my pass. Also, btw, these scooters are way heavier than any of their competitors. If you want to lift it from the street to the sidewalk, forget it.

Updating my review: Payments no longer work. Tried Multiple cards from different banks AND Google pay. Nothing works anymore and now I can't rent a scooter at all Good parking, ride, and pricing, but the way it calculates minutes is terrible. It will always round up even if you're 1 second over. I literally had a ride that was 8:01 and it charged me for 9 minutes.

I downloaded the app. It would not verify my number to create an account. Customer service has been unreachable. I have spent 2 weeks dealing with this to use their scooters. A lot of lost business. Lime or Dott was much easier and better to do business with. Update: per the TIER reply I sent and email to customer support. Other than an auto reply, they have never responded in a month of inquiries.
