...it smelled like burning wires.

For me, it was the smell of BBQ! Lasted about 1 year and 3 months. Now, I occasionally think charcoal is burning, but faint and not often.
Heard about others who said they smelled sulfur, like a match being struck.
A year? Holy cow! I gotta put up with this for a year? Well, that was in Jan, so I got 5 more months.
