As some who've owned products that this igniter fits likely know, these are typically only good for approximately 12 months for cooks who acually use their ovens.  We've had our Caloric for nearly 20 years now and have replaced igniters like clockwork (well, calendar work? haha) around every 12 months (some haven't gone even 12 months).  While it's hard to say if we've used the oven less this year or not, this igniter has now lasted 16 months and is still firing it up!  It physically matches the majority of others we've purchased over the years, appearance wise, but for whatever reason is exceeding expectations (whether we just just got lucky, or with age somewhat slipped from using it as frequently --which while I don't think is the case, I can't say).
