"I think for version 2.0 you should try to implement a carousel-type design (similar to those machines you would get a crappy egg salad sandwich or an 8 oz. carton of expired chocolate milk), thereby removing what appears to be this machine's inability to dispense any inventory at any time (i.e. different colors/weights unavailable until they reach the front of the dispenser coil). Everything else about this is a total WIN. Great job, and keep it up!"
