ETA hand2mind Linking Pop Cubes Educational Counting Math Toy (Set of 100)

👍

They hardly click together. I thought my autistic son would love these but they are so hard to try and put together. Very cheap quality. Spend more money on better ones if you want to purchase these

Bought for building fine motor skills. It does exactly that.

I bought these after my son used a similar product. We were not able to locate a brand on the product, but when I found these on Amazon I thought I'd found what we were looking for. I was severely disappointed with the quality of this product. The plastic is very thin and light, and the fittings are inconsistent. Some are very difficult to take apart, and others simply fall apart when you put them together. Immediately after opening the package I could tell from the weight and feel of the plastic that these were not the product I was hoping for. The cubes my son had been playing with snapped apart with a loud "pop" which he enjoyed very much. When stacked, some pieces fall off, and when you try to snap them apart the whole stack flexes before breaking into pieces and make no noise. If they actually all stayed together I wouldn't have an issue to complain about publicly. In my opinion, "interlocking" cubes that don't interlock are useless.

Rough edges from the molds. Bad quality control they could of sanded or smoothed it a bit.

These are simple plastic blocks that interlock to help kids count and create. The blocks don't always stay together or they are hard to push together, so other brands may have be better quality.
