The user interface was very clumsy and difficult to figure out how to use. The online reference manual provided some help but I couldn't even figure out how to slope the grounds and the housing choices were terrible. I spent too much time trying to get the right house, resize it, build a deck - it was very frustrating and time consuming. I never got to do the thing I wanted to do and that was design my landscape!After two hours I gave up and tossed the software.
