Tragic puzzle like almost all of the series. It took me about 30 seconds to solve it and putting it back in place took 2 days! When you try to put it back in place, obviously you have to push it. As one can understand, pressure and wood do not go well together, so the risk of breaking is sky-high. Also, the wood, unlike a good metal, opens up, and its assembly is not stable since in two points you can theoretically have the same tolerances, and in one, the two pieces can be stuck together, while in the other, they can be loose. If you attempt to put it back in place, all the pieces will be ready to come out until the last one is in, and in some pieces, you might find that they are completely stuck as soon as the last piece goes in, while in others, everything is loose. When putting it in place, everything was so tight that I thought I had done something wrong. Searching on YouTube, I saw that everyone had the same issue with pieces that were completely loose for some and completely tight for others. Generally, the only joy this puzzle offers is the visual aspect; everything else is disappointing. At least this one comes varnished, unlike the barrel, from which you will later have to remove wood pieces from your skin!!!! Either buy 2, one to solve and throw away and the other to stay on the shelf looking nice, or none at all since it is not a good puzzle. If you want good puzzles, Huzzle is the solution. Metal, with plenty of difficulties (real ones, not like this nonsense) for you to choose from.
