AZEN 200PCS Building Sticks Blocks Toy

I like the colors and multiple shapes. And the fact they compatible with other similar toys. However the magnets aren't strong enough in my opinion. A one story structure will stand okay. But usually if you try to add another story it collapses. (Last picture) A SMALL multi-dimension will work, but nothing to elaborate. The kids end up becoming frustrated and quit playing. Probably a toy best for toddlers to 4 yrs. My 6 & 9 yr old become frustrated.

The set does come in a plastic storage box which is nice. However, the bars are a cheap hollow plastic. The magnets aren't secured well in the bars and they aren't strong enough to support the balls. We tried to build a cube following the instructions a number of times only to have it collapse on itself. We really wanted to like this as it came with various sized pieces and allowed for creative builds, but it is not worth the money.
