If they had something other than the weight of your storage items to hold the bottom in place, like a locking clamp, it would be a whole lot better. This is because if you pick up wrong without anything in it (or very light storage items), it begins to fold back up and come apart (I don't mean it that it breaks, it just goes back to the state it was in when it was shipped). If it was not for that, I would've given it 5 stars.
