Rowood 3D Puzzles for Adults, Wooden Model Kits for Adults to Build, DIY Mechanical Gear Building Kit - Perpetual Calendar

This was really cool. I enjoyed putting it together. The difficulty rating is 3 out of 5 when honestly, it could be a 2. It makes me excited to check out their other products.

I bought this for my 12 year old grandson for Christmas as he loves all types of puzzley, gadgety, hands on, do it yourself, buildable things. I thought it would take him about two weeks to finish, but my son informed me that he finished it completely in less than an afternoon! He is pretty brainy though, so if I get him someting similar in the future, I reckon I'll search for something even more complicated! He does use it on his desk at home for his daily calendar, though, so I'm very happy about that!

There were no dislikes to this item. It was fun to put together. I love it will be buying more.

Too easy to assemble - not enough pieces to make it worth the money in my opinion. “Programming” it to show the right date was tricky as well. I don’t think it took 30 minutes to punch out pieces and assemble which was a little disappointing. Other puzzles from the same company that have more complexity are well worth it - I just don’t think this perpetual calendar was in particular.

My husband loved it as it was his Christmas gift. He said it was easy to put together and loves it.

Very cool looking, took about 30min

grandson is 13 had this together in no time great gift.

I bought this to try out as I have made many metal earth models. I was impressed by the laser cut accuracy of the fit of the pieces. I loved building it. The only slight improvement would be if they could make the burn of the designs darker to see the art and numbers.

My son was very happy with this Christmas present. He said it was fun to put together and thus far it is keeping time well.

It was fun to do. A bit smaller than expected

Beautiful puzzle! My stepson loved it

Arrived next day! was a lot of fun to put together. All pieces were included and it looks super cool sitting in our living room!
