This is a solid kit with several uses, and easily modified. The pieces are for the most part well sized and free of flash. The silos themselves go together quite well, with only the smallest of visual seams. Some of the pipes on the top don't quite line up perfectly and lack guides to ensure a correct fit. There is no guide for lining up the elevator at the top of the silo so test fit everything first before gluing. The instructions are very poor, consisting of pictures only and no written instructions. Sometimes this is not a big deal but in this case it is. Again, test fit first! Once complete it looks quite good. I heavily modified mine, adding a second floor office area above the unloading shed, complete with exterior walkway, ladder and stairs. I also added several LEDs. This was not that hard to do, just needing some patience.
