CubicFun 3D Puzzle - Large Saint Paul's Cathedral 3D Puzzles for Adults - Half-Opening Architecture, Enjoy Interior Views - Anniversary Wedding Souvenir Birthday Easter Father's Gifts - 643 Pieces

I was skeptical due to the low price, but I found this puzzle was perfect. EVERYTHING fit together, everything popped out of the puzzle sheets well, it looks great and was an awesome build. It was definitely difficult, but I had no problems or questions going through it. I'm 34/m and it took about 12 hours to build. Would definitely recommend and will certainly buy more of their stuff.

This was so much fun to put together. The pieces are strong and its very sturdy once put together. There are a few pages of pieces with adhesive backing, a clear plastic sheet of pieces for all the windows, and then like 17 pages of regular pieces. Also - it wasn't missing any pieces - that was the best part! Definitely highly recommend this one! Can't beat the price either!

I loved this projecct! This product was delightful and interesting yet also challenging to build. It's a 5 star for how much fun it was to construct, but 4.5 in "sturdiness" as the bottom slide tabs are showing major wear&tear after only 6-8 times opening the 2 halves. The directions were good and followed exactly (am an amateur still learning techniques in miniature), and it turned out to be not perfect (due to my minor mistakes, yet quite beautiful. Worked slowly, enjoying the learning process, it took @3 weeks at 2-3 hrs per day. (Build would have gone much more quickly had I not spent time wiring it up with LEDs. Had no idea how to do it but worked it out inch by inch.-glad I did as the lighting is fabulous and shows off the windows).

Love it!

This model never stopped impressing me. Everything fits together with precision. I used Elmer's white glue to assemble practically every piece. This isn't a model you put together more than once. The glue makes everything sturdy and solid. I did find one mistake in the instructions. They seem to have omitted the instructions for placement of the dome windows which are in a strip of 8 or so. I believe they were to be installed between the dome pieces. It is nowhere in the instructions. I had already assembled the dome until I realized it and tried to slide the strip in without taking it apart. To no avail so I left them out. Nevertheless the cathedral came out stunning. This was the third Cubic Fun model I completed. And like another customer I read in a review, I was sad when I was coming to the end. Loved every minute of the assembly.

This isn't a 3-D puzzle like the ones offered by that other company, but is more like an assembly kit - no way you could put it together without step-by-step instructions. But for that you get something that is much more intricate and detailed and feels like a real model. Very high production quality and it's amazing the amount of work that goes into producing this. The cuts on the board have all been good, and the pieces have all come out cleanly. The pieces hold together pretty securely without any additional adhesive. It's an impressive project and worth the time!

A very nice model that is easy to put together and looks great.

I really wish there were more options for this brand of puzzle. The quality is spectacular for the most part and it was a lot of fun. I did it in a weekend. I couldn't stop. I hope they come out with more options for historic buildings like this.
