We needed these because our dog had turned on the gas stove while we were out of the house, trying to kill us or himself, we're still unsure. We had first bought a set from Baby's R Us which were completely clear plastic. We went through 2 packages of these, as they were very easy to break, and a little bit difficult to open (forcing them open was the reason they broke at the "hinge" which would also come apart once opened.) These are 10x better. The rubber opening makes it smoother to open and the hinge is so much better. Plus, they look much nicer than the previous set. We haven't had any issues with these, and the dog's plans for mass murder have been averted.
