KAILIMENG Metal Puzzle, Brain Teaser Metal Wire Puzzle for Adults and Kids - Mind Game 3D IQ Jigsaw, Set of 8

Pros and cons time!!Tldr: a lot of fun and use but quite small and a little flimsy. Best for childrenPros:Variety: well it's a combo pack your getting 6 puzzles.Difficulty: they range from stupid simple to about a 6 on a scale from 1-10Usefulness: the best use for these is developing fine motor control and critical thinking in children. And honestly it works great for thatCons:Size: they run rather small they fit great in a child's hand thoughConstruction: due to the size they are a bit flimsy and because of this some impatient people will brute force some of them...So in depth a little. I bought these to really start working on my 5 year Olds fine motor control skills and critical thinking. It was difficult to get her started but once she figured one out I couldn't keep her away from them. I give them to her one at a time and when she has mastered one she gets a new one. This is the best use case I can think of for these.I let a few friends try but they quickly became annoyed and brute strength a couple. Luckily they weren't damaged in the process.

Fun set of puzzles that are decently made for the price. The tray they come in is junk, you'll need to find another place to store them.Some of them are easy while a few are pretty challenging. Would make a great gift for a older child/teen/young at heart adult. The metal they're made of is rigid, but can be bent if moderate force is applied. This and the cheap storage tray is why I gave them 4 and not 5 stars.For the price it's a good buy though.

Some of these are easy to figure out. My 7 year old nephew took one out and solved it in a few seconds. My 6 year old niece picked up another and had it figured in just a few more. There are a few that have the same or similar solutions as others too. And yet there is one that we just haven't figured out yet. Nevertheless, these were a fun little challenge for the little ones and a great way to stretch their brains without having to teach them the Rubik's Cube. There should be more toys/puzzles that are built to challenge spatial reasoning skills for youngsters. This one is a nice little starter set before graduating to more challenging puzzles.

This is a great set of puzzles. The diversity in geometry allows for anyone to get stuck on one specific shape.... I am (the "M"). The spring will intimidate most people although it is not the most difficult.It draws the attention of family and friends, even cats, of any age and background. Everybody can play at the same time. I would recommend to hide the solution page though.The puzzles are sturdy and well made.

Good puzzles, but they're kind of small. Small size makes it hard for adult hands to manipulate, which takes some of the fun out of it.

These are so fun to play with.They are small, which can be a problem if you have big fingers (which I don't). You could carry them around in your pocket if you like, but they're big enough for me and my friends to use. The instructions that come with it are very difficult to understand but if you need help solving one, you could always google it. Overall, I had a good time with these puzzles and am glad I bought them.

Wonderful little puzzles, well made. These are a bit smaller than the other similar set (Vktech) I bought, but have an additional puzzle - the spring - that is really elegant. They are also shinier and thus more attractive to play with. Be careful if you don't want spoilers - they come with solution pictures (although the solutions are not perfectly easy to visualize). I was worried that they would be too fragile but they are not - you could, certainly, use strength bend the items to cheat but you would know what you were doing was cheating. Good fun. We enjoyed them in my office for a good while.

My uncle is always telling me to think more like an engineer, so I got this as a gag gift to test his thinking.I struggled with it, but he was able to do it pretty easily.It was a cute present.All the solutions are on the back.The set was much less expensive than buying the individual puzzles from other websites.All-in-all, no complaints about the product.
