This Kibri kit is a delight to build and very satisfying. When it is all finished all the lines work and the crane and bucket can be operated. Although there are many small parts that require a steady hand to install and glue together, the instructions are clear. Be sure you follow the assembly sequence as you may find a problem if you do the assembly out of sequence as this may cause a later sequence to be impossible or, at best, much more difficult to complete. The one step of attaching base of the cab to the tractor tread wasn't clear but I found that the part on the bottom just pressed into the cab base allowing the cab to turn on the tractor tread. All in all, a very well manufactured kit with clear instructions.
Kibri produces quality products, and this crane is no exception. It perfectly outfits the Kibri barge and is the foundation of a mini-scene on my layout.
