Tri-Mags Magnetic Puzzle Toy, 48 Piece STEM Learning Toy

I bought these as a gift for my neighbor's 2 year old grandson several years ago. He just turned 5. She also babysits my granddaughter and a few kids after school. All the kids love playing with them. The age range is 2 years old to 11 years old. I would recommend getting 2 sets. Forty-eight pieces sounds like a lot, but it takes anywhere from 4-6 to build a simple shape. They are durable, none have cracked or broken. The colors are still as vibrant as they were 3 years ago. They are still a favorite of all the kids. I would buy them again, and would certainly give as a gift again.

I bought this for my son. This is perfect. He plays with the triangles to make different puzzles. We bought the one with more pieces so we can have some in the car and some at home. He no longer asks for the tablet or phone in the car. We take this toy into restaurants, it is perfect and provides him hours of fun. He had this in his afterschool care and knowing summer was approaching, I bought it and we are so happy with it!

I'm a UI, UX, and 3D Graphics expert and was looking for a way to visualize rendering of "Marching Tetrahedrons" and "Simplex" geometry. Searching on Amazon for "tetrahedron" or "simplex" was a complete and utter failure as manufacturers and 3rd party sellers don't know how to properly tag toys so us professionals can find them. I saw a post on "Procworld" entitled "Simplex toys are the best" but couldn't find the Brand/Model of the toys until a colleague saw the picture and recommend that I give these a go.These toys are the perfect physical model to help with visualization!The box has 48 pieces which comes in the shape of 2 cubes that consists of 24 pyramidal pieces per cube; each pyramidal piece has the pyramid base dimensions being 2"x2"x2.82" and a 1.5" height. Each piece is also magnetic. The magnets are not particularly strong but they (barely) do the job. For a more rigid structure you'll definitely want to use double-sided tape. The 1/8" magnets are long the edges so I don't know how easy it is to find stronger replacements.The pieces are nicely color-coded to help distinguish them from one another and come in the following 6 colors:* Red* Yellow* Green* Blue* Cyan* MagentaSadly from a distance the dull cherry red and magenta (purple) blend in. I wish the red was much brighter.Having "only" 6 colors isn't a deal breaker for visualization but I also wish there 2 extra colors (for a total of 8) such as Orange or White. The ultimate would be to include 8 Transparent blocks so one could see the middle. If future editions don't include transparent blocks there is always the option of looking into 3D printing for the more serious modeler.The pieces aren't lightweight so they don't give that feel of "cheap plastic toy Made in _X_". Now I could see durability being an issue for children that play rough but as a professional I'll be careful making the different geometrical shapes.Pros+ Big pieces+ Magnetic+ 6 Color Choices+ Good bang/buckNeutral= Decent priceCons- No transparent colors- Limited colors; dull red instead of bright fire engine red- Durability might be an issue for childrenStill a great product!

Absolutely love this product. I had found an old incomplete set that was given to me as a "stocking stuffer" many years ago and, feeling nostalgic, checked Amazon to see if by any chance this old, very basic toy was still available. Lo and behold, it was and relatively cheap, too! I ordered it immediately and was not disappointed; it is exactly like my old set. I keep it on my office desk to play when my mind needs a break. Love it! (Just keep it away from the computer or any disks - magnets!)

Got this for my grandson turning 3 who already has everything, and turned out he LOVED these magnet blocks and even six year old sister couldn't resist them.I had some trepidation on ordering, since the reviews were mixed and the pricing was less than some similar magnet toys here, but this toy was a hit.its fun and absorbing and helps with the child's spatial reasoning!

Our 3yo boy plays w/ these and pulls them out on occasion. When he does play w/ them, he can get into it, but overall this isn't something that is super intriguing for him. He very much likes shapes and building things, but I don't think he sees the 'payback' when building something. I can see how/why the magnets are placed as they are, but he does get a little frustrated when he wants to do something not necessarily conducive to how they 'mate'. Not an issue w/ the toy as it isn't constructed to be more of a wide open format.The one thing that I wish was better on the pieces, and see this w/ the boy too, is if the magnets were a little stronger. I think it'd be more satisfying in a tactile sense if so. I think too that the shapes constructed would be nicer as a result; e.g., if you put these things together, and not necessarily a big object, you will not be able to lift by a couple of pieces and have it stay together.Overall, it's ok. I wouldn't buy it again based on what I've seen, but it does get some use.
