Very easy to use. The only think Id like to see that isnt here is a notes function. That way you could keep track of what level youre on in a multi-level garage, or know what lot name/number youre parked in - even row and space number if you wanted to be that meticulous about it. Knowing what level youre on in a garage or parking structure is pretty valuable when all the floors look alike, and knowing the lot name or number is valuable if you need to actually take a shuttle to wherever you parked.
