It has a great visual look, but I got really confuse when I start to adjust the filters on the left hand side. The phones icons started to jump to different spots on graph that does not seem to change. Let me give you an example, as I changed the filter of the RAM from 1GB to 2GB, the icon Samsung Galaxy S5 G900F 4G LTE 16GB jumped over the icon for Samsung Galaxy S5 G900FD DUOS 4G LTE even though their specs exactly the same. When I saw that, I concluded that their screen sizes changed due to memory configuration as the x-axis of the graph is screen size. Yeah, I know it is a bad conclusion, but that what the graph says.
