It's very easy to use for my clients who are designers / architects as it allows them quickly create their own 3D models without having any technical knowledge or experience required (as long you have an internet connection). The ability to share your model online so that others can see how they will look like before construction has started also helps me save time when I'm working remotely from another country than where our client resides - which means this software really saves money! There isn't anything at all bad about montage but maybe some more features would be nice such us being able export directly into SketchUp instead of making 2 steps between different softwares first then exporting again back onto sketchup etc..
