I move them all the time, in my neighborhood people leave them on the wheelchair ramps at crosswalks all the time. I move them to a more reasonable location nearby.

They are heavier than they look and have an alarm. The alarm turns off when you put it down.

When I downloaded the app, it had instructions that when you were done with your rental you should take a picture in the app to confirm it was parked correctly or potentially face a fine. It doesn't seem like that is enforced at all.

I like the idea of them esp now that Scooby (RIP) has left Pittsburgh, but I think the implementation still has some kinks to work out.
