I like that it's able give me information about how certain areas will look in real life, but also gives you an idea for what your rooms are going up against so as not make them too dark or over-bright! It can be difficult at times because some things aren't immediately clear when looking through all aspects (eg - if there was more info relating specifically to walls/corners). If planning new homes with existing designs then this product really helps narrow down ideas quickly without having to go back & forth between different software applications multiple time which saves both money AND precious design hours. When using radiances we're given better insight into our room choices before actually getting out hands dirty during actual building work!!
