My kids have 800 of these big, giant LEGO-like blocks! (That's 10 boxes.) Not all at once, but when we saw how much fun it was, we kept getting more-- for birthdays, 'good grades rewards', etc. And having generous grandparents helps... :-)
They are used constantly. These blocks -- very high quality! -- are so much MORE than just a toy! It's astonishing what my children come up with... They make life-size things like furniture, or playhouses big enough to go inside. Many things are sturdy enough to climb on. Their friends love to come over and build, then they all play with what they made. For hours.
Like they made a stage, and then had a talent show. With costumes.
All ages enjoy them but they really resonate with the 6-12 crowd.
When it comes to toys, I'm real picky, and no push-over. I can say "No!" if I don't think something's worth while. So if I buy 10 boxes of something, there's a reason!
