Robust but needs polishing

The app is fun and it is really cool to see your build before you actually do it. The reason I gave this app 2 stars is because it is in need of some SERIOUS polishing. The app runs incredibly slow moving between components (i.e. Lower exploded to upper receiver exploded). The brands available are ok but I feel like there should be more brands and I would like to see the quality of the user interface improved. All in all great app and I will give 5 stars as they update and improve.
