This block set more than met our expectations. It is a great set to compliment other Haba block sets, but has enough blocks included to stand alone. It's really nice to be able to add some stability with the clamps to our sometimes precarious block configurations, and it is so cool to be able to turn blocks into cars and trains and trucks so easily. There are more possibilities suggested in the pamphlet that comes with the set than what is advertised, which is nice. The one thing I thought odd was that two "cars" are made of two blocks permanently joined together instead of all the blocks being free to be arranged and interchanged by the child, that's the only thing I'd change.
