I was surprised as I thought it would work better than it did.  I bought 2 and one actually has the magnet on backwards.  I also ordered TWO packages of 2 but only got one package and was charged the price of 4.  I am not sure it was the way it was worded on the site or what but I was not happy.  Over all giving it 2 stars is more than deserved.
