I go off the theory anything can and will fail at sometime but will still last for years and at 15.00 to replace even every 5 years is not bad at all but I would bet it will last longer. Heck I have a normal main water valve that is leaking in my house and that's something that gets turned a few times in a lifetime. It's rare for them to leak but only after a few years it is. That's just my thought but if something really is much much better maybe it would be worth it.
