This was very fun, challenging but not to challenging.Price is perfect, the build quality is excellent. A great display piece too. Would highly recommend. Great puzzles from the maker.Mike ✌🏻

I bought this for my husband for his birthday- while it is a little smaller than I expected, it’s a beautiful puzzle and makes for a great decorative conversation piece.It took my husband a little over an hour to solve and a half hour to put back together. I was able to solve it in just under an hour, but it took about an hour and a half to put it back together (you’re more likely to accidentally solve it again than get it back to starting)!Our family were all pretty captivated by it as well- everyone wanted to fidget it with while visiting and loved how it looked!I highly recommend this for anyone who loves a good puzzle!

It took me about an hour to solve but once you get the pattern, it's so exciting to start moving everything with purpose. Once you solve it, it takes maybe 5-10 minutes to reset it and do the pattern in reverse. The only sad part is now the secret is ruined and it's not as fun to play again, but fun to watch others try!

I took the picture up close to avoid spoiling for the enthusiasts. Fun puzzle, but I think the plastic hole for mine was cut too small for the ball. I'll chalk this one up to manufacturing error.Before you all go, "you didn't solve it then," I even double checked my solution. It's correct, the ball does clear both wood pieces, just not the plastic wall. I was even tempted to take it apart to be sure that's what was happening, but it's too well made for that. I guess one benefit is I'll never lose the ball. 😁

This puzzle is ver nice, it would make a great gift. It is a very high quality product. Nice weight, high quality wood, acrylic and metal connectors. Smooth to glide and slide moving pieces. The color finishes on the different bottles are also nice. I don’t think it is difficult to solve, just fiddling and frustrating. But, once you solve it you get a great feeling of satisfaction.

Bought this for my 15-year-old grandson who figured out how to release the ball bearings in about 10 minutes. Was hoping it would challenge him for a bit longer, but he had fun and he likes the way the puzzle looks. He promised to show his younger sister how to solve it.

Like another reviewer, my puzzle came without a critical slot in one of the pieces which has rendered it unsolvable. (The wooden piece on the right). But on the bright side, I’ve enjoyed beating my head against this puzzle for over two years—not realizing it was unwinnable. It was only because the screw backings came loose enough that it nearly came apart that I finally looked up for images of how it’s *supposed* to look. And that’s when I notice the manufacturing flaw. So, for anyone purchasing the puzzle: be sure to doublecheck that all the correct slots are present before giving this as a gift.

Great puzzle. Once you figure out the pattern, its easy to solve. But, that doesn’t make it any less fun. The two step forward one step back pattern is satisfying. About an hour to complete. Overall nice.
