This was a beautiful addition to our collection of connetix. My husband and I have fun building complicated structures for our little one to play with. I love that it is transparent , magnets are better than other brand, works with other brand. It has six balls included ( hope they sell extra to add). CONS, lots of patience in building and when taking it off as it can cause the edges lock show some breakage ( only happened in one piece), and some pieces are easier to attach than others. We were able to pre-order and update on status and changes was great from shop.
I recommend this product
