Product review (4 stars): You need this unless you like to wear wet clothes.
I never give anything 5 stars, afterall, it's only an igniter.  However, after installation, this igniter caused my wife to become excited for some reason I have not figured out yet.  I even got a nice dinner, a kiss, and a comment that "you can fix anything, except stupid", to which I replied "gimme a roll of duct tape, and if I cant fix stupid, I can keep it quiet".  I was eyeballing the cat at the time, and my wife reminded me of the cat's real name.
