Product review (5 stars): Just as others have stated, it works great at a fraction of the cost
I was quite happy to with my wife who was able to research and I did the work, which was actually pretty simple. My wife was dreading calling the Viking $peciali$t,  so she looked up the information, prepped the oven, and I did the ordering and installation. What a team. The results have been explained by others. These ignitors heat up pretty fast and turn on the oven quickly. I also changed the burners, which showed holes, one each by the ignitor. Probably didn't hurt anything, but the wifey complained about a thumping sound once in a while.  So, while I had access to that area, ordered the burners, that were on sale and cheaper than anywhere else at Viking parts store. Ours is VGIC305. I had to cut the terminal, but didn't hesitate, as that seems the only way to connect. The only thing, is that the filament in the Viking ignitor seemed sturdier, but that is hard to assess. Fit just like the original. GO for it!!!
