Wood TrickMad Buggy Car 3D Wooden Puzzle for Adults and Kids to Build - Rides up to 25 feet - Detailed and Sturdy Design - Engineering DIY Wooden Model Car Kit to Build

I think you should be at least 20 years old.

I purchased the Mad Buggy. This project took me a total of 16 hours. The pieces are made to fit very tight. I wish I had a little more finger strength, but eventually figured out that the pieces fit easier if I sanded every surface where it fits together. I used a sheet of 120 grit and never had issues with over sanding. The pieces are sturdy but still fragile. Sounds contradictory, I know. They are a soft wood like balsa, but there are three thick layers of it pressed together. I got a little to comfortable at how well they popped out of the sheet by number 70 and broke one. I was able to repair it with glue...and realized when I was almost done that there was a sheet containing some spare parts just for this reason. The instructions were detailed pictures that I found simple for the most part. I had to use my brain a bit when it came to the gears, and was extremely happy when it worked when I was finished. Because of the small pieces, complicated gears, and patience required, I would not recommend this for younger children. A teen looking for a challenge would probably love it though. I will be buying more of these. The seller shipped the product quickly as promised and would buy from them again as well.

La qualité du bois, du plan et du montage font de ce puzzle un plaisir à réaliser. Et le résultat et plus que sympa !

When removing the piston connecting rods. Be careful. They break very easy. I used super glue and that seem to work good. Otherwise, a lot of fun,

Ordered for Christmas and it arrived on time. Was a little bit expensive for a puzzle. However, the idea for these are great for adults to enjoy as a puzzle. Receiver of the gift enjoyed it.
