This was a fun find for the kids. We're always making forts (or \"houses\") with couch cushions, chairs, and blankets, but they are always low profile. With the 80 rod, 40 ball kit I was able to make the kids the igloo build but two levels so they can even stand up in it. They are 4 and 2, and the rods and balls are quite sturdy and stand up to the pulling and bending that are inevitable att hese ages. From the feel if it, the rods will probably break if purposely bent too much, but my kids aren't that strong. It comes woth some cheap plastic clips to hold blankets and sheets, and the clips work for their intended use. You can build the designs from the examples that come with it, or if you have older kids let them explore with making their own designs. There is a lot they can build with this! The bag it comes with holds everything well, but the design is random, albeit cute (it says \"monster\" and has cute little monsters on it). I picked this up on a whim and my kids are very happy with this surprise. The price is right (for the 120 piece kit) to make for a great gift at a reasonable price.
