We open ours quite frequently as well. The only thing I don't like about ours is that it's either all the way open or all the way closed because of the way the support works. Most of the time it's not a problem, but it is a limitation.
Also, ours has a piano hinge all the way across the top, so I'm not worried about it falling out...
