It's hard to rate an item that either works or doesn't work. They have an internal thermostat so they won't burn out as quickly if the relay sticks or your extra toggle switch stays on. I can't say anything about the service life yet, the Meyle glow plugs I use have generally lasted less than a year and have been replaced when worn out.
