The best thing about this platform is that it has multiple devices which can be used for product development in various layouts or orientations, even if they are not physically available to use! It is also very easy to edit any existing design once you have created one using their toolkit as well. Their support team could do with some improvement though, I had asked them few questions regarding designing of my own products but didn't get an answer back until after almost two weeks (and then only through email). You don’t need to worry too much when working with these guys - just give them all your requirements right from start itself so that things go smoothly without having problems later down the line. We were able to develop our website layout completely offline before launching into production phase since we knew exactly how many screens would fit onto each page at final stage.
