Pretty good set. Makes nice-looking pieces and isn't what I'd call "difficult." I would also not call it "quick to build" or "so easy a child could do it." I've done a fair amount of papercraft in my day and this is about average as far as time investment for the quality of finished product (which really is quite good). From the description, I expected to finish a piece in about ten minutes. In reality, smallish tabs make it take a lottle longer. Also: some of the lines (particularly the score lines) are quite faint. To be fair, I printed the kit on fast mode in greyscale. To be equally fair, I printed my Fat Dragon DM Screen 2 the same way and had no such trouble seeing the lines. So not disappointed with the purchase in general but a little annoyed at the sometimes-hard-to-see lines. Would definitely recommend. Probably won't buy more but not even a little remorseful that I bought what I bought. I will use it over and over through the ages.
