Not sure why I waited so long.  I had bought a plastic one for $6 but don't do that.  This makes you look legit.  I feel like it would be more handy for it to open from the bottom up??  I really don't understand why anyone would want it to open the way it does.  But I make it work.  It's very sturdy.  I also don't like how slick it is because it falls off my seat.  Perhaps rubber bottom in the future so it sticks to a surface?
