Product review (1 stars): Pairs nicely with fire
Purchased the set in January of 2014.  Worked great until the end of June 2015 when failure of the upper thermal fuse failed.  Not just a little fail mind you, but catastrophic: flames and smoke, the whole nine yards.  Fortunately my wife was in the immediate vicinity and damage was isolated to the fuse itself with some minor extension to the wires.  We rarely run our dryer on the high heat setting so I cant say we were stressing it.  The fuse THAT one replaced was well over twelve years old and was of a different design but I was told by multiple sources that this is its replacement.  One would have to question the overall QC (quality control) thats taking place here.  Just another testament to working smoke detectors, folks.
