"The set in general was great! I bought it because the mechanisms interested me and it had parts that I didn't have in my collection. The build took more attention to detail than I thought and the arm was more complex as well - both good things! It wasn't over quickly which makes it more enjoyable.
However when adding a few pieces to the vehicle's body, there were several that didn't alight properly when placed beside eachother on one of the technic axles. The hole for the axle must be just a few degrees off. Noticeable only if you look closely. I wouldn't attribute this to the set itself, just some unfortunate mixing of parts."
