The user interface is easy to use, very intuitive; there's no need for training or learning curve when you first start using it because everything works like magic! It has been great so far - I haven't found any downsides yet that could be improved upon (at least not by me).
There are some minor bugs here & but nothing really serious as of now. We're trying out this software at our office since about 2 months ago with good results thusfar- we've had an increase traffic flow from parking spaces which was hard before due its lack thereof.-.
