I purchased the Fire Magic to insure that my new natural gas grill was not left on accidently. I've had it a few months and it has been working great.I was concerned about durability so I installed it with maximizing it's lifespan in mind:I installed the unit upright in a sheltered location. The dial is just plastic so you may want to plan for some kind of enclosure if it will be exposed to the sun and elements.I also installed a manual shut off value inline before the timer. This allows me to turn off the gas without needing to turn the timer "backward" hopefully reducing ware on the timer. It also will make it easier to replace should that be necessary.Having automatic shutoff for a grill or set of logs is such a obvious safety addition that even with some longevity concerns I can't help but recommend the Fire Magic timer.
