So far this little cart is working out just great.  We got it put together just fine and without any hassles but I haven't really used it outside just yet so I can't really comment on the functionality of it.  I did roll it around a bit inside the house and it seemed just fine.  I haven't placed anything on it yet so I'm not sure how sturdy or not sturdy it is, but I really don't foresee having any issues with it.  It seems sturdy and well designed.  If I have any issues with it once we start using it then I'll certainly let you know. As of right now, so far so good!
