My 6 year old and 7 year old love this toy - they named it their favorite Christmas gift. My husband was skeptical - he thought they'd get frustrated trying to build with it, but not at all. They took to it like a duck to water and loved building new things. If your kids are always begging you to take apart your sofas to make forts, you need to get this toy!One nice thing if you're gift hunting - if you bought this for someone who already had it, no problem. The kids would just be able to build bigger forts!I'm thinking I might add some inexpensive shower curtains to the bag for more options.It comes with a storage bag for the parts - it would be simple to bring it to grandmas.I've been impressed with every Cranium product we've owned. They are high quality, well thought out, simple to figure out, kid-friendly and parent friendly as well.
