Just had an old window/door sensor fail but this one had to be about 10 years old!!! this one was made under the old Magnavox name and I think I paid 20 bucks for it so no complaints here especially considering it was made in China, if the x10 versions last that long at 3 bucks a pop well I guess that would be a great deal. Only thing I hate is that when they fail they give false alarms, just imagine being at work or the show when that happens and you have to rush home. Anyone one know what the normal life expectancy is on these unit's?
