I was suprised at the quality of the plastic and components for the price. It's actually become something of a god-send and I would recommend to anyone with a micro kit and breadboard to make life easier. It's just a shame the packing was poor and screws and washers were loose in the box, which meant some of the plastic spacers/washers were missing, which was not a big deal but just annoying
