My wife got this for my son when I was deployed.  She can not stop going on about how hard it was to put together.  Her solution and the reason for this review is to let other parents know, "just take it to [...], spend [$], and pick it up fully assembled two days later.  They even put all the stickers on and everything".  After all that, our son loves the thing.  Hates to get out of it, can't keep him away from it, and he even loves to push it around.  Great gift, but horrible to put together.
