UGEARS Book of Secrets 3D Puzzle Box - 3D Wooden Puzzles For Adults, Fun DIY Craft Kit - Steampunk Treasure Box Wooden Model Kits for Adults to Build, for Hobby Enthusiasts

Very well made with clear instructions. Need to make sure all burrs are removed and gears etc. are waxed and tested before moving on to next assembly instruction. Quite complex but very rewarding to do and works beautifully if care is taken with the assembly. Highly recommended.

Bought for my 11 year old grandson as a Christmas present. It does say that it's intended for adults but he loves a challenge. He spent six and a half hours making it, with no help from any adults. He thoroughly enjoyed the whole experience of building it by himself and though it was indeed a challenge, with lots of intricate parts, that was part of the fun. His comment on this: "It's amazing". I must add that the finished article looks exceptional and works really well.

Puzzle box was good fun building, but beware some parts are easily broken. If you do break a part and cannot repair it, go on ugears web page for free spare parts.

Assembly was medium to hard so make sure the instructions are read carefully and make use of the QR code videos. It works really well when finished and if pieces are not quite right, the other pieces will compensate. Looks really good when finished.

I bought this as a birthday gift. It comes securely boxed, with full instructions and the parts are, as far as I can see, sturdy wood. I have not interfered with it too much, as it is to be a present, but it looks very intriguing and I'm sure the recipient will like it.

Hard to fault Ugesrs. Take your time, follow instructions and keep testing movement

Quite expensive but well worth the money. Great fun to make. The engineering is amazing, precision manufactured with clear instructions. You need strong fingers and patience. The finished book/box is good to look at as well as being a practical item. Hats off to the designers of this brilliant puzzle box.

Seeing the pieces go together, how the dials all work, every movement, this is a great peace to build, it does hold a few things, and is a great design,

It was great

Genial

Superbe objet !

To mój pierwszy kolorowy zestaw od UGEARS. Wciąż jestem w trakcie jego budowania. Ale dwukolorowe drzewo wygląda pięknie. Polecam kupić.

Ein beeindruckender Bausatz. Wunderbare Konstruktion, präzise geschnitten - aber nicht leicht zu bauen (Teile vorsichtig lösen und mit Geduld und Gefühl zusammenstecken - und: unbedingt an die Anleitung halte!. Aus meiner Sicht nichts für jugendliche Ungeduld.
