Query: not worth money

I bought this as a Christmas present for my 4 & 5 year old boys last year. It lasted a weekend. This was Christmas 2011. Now looking at the reviews (which I wish I would have read ahead of time), I wish I would never have wasted my money. It is no more durable than it was back in 2006. Poorly built.
