Product review (5 stars): Works ok, but didn't fix the problem.
The igniter works just fine, but it turned out it wasn't the problem, it was the gas valve assembly.  Our oven was taking over 20 minutes to get up to temp and the description of the way the circuit works made it hard to tell if the problem was the igniter or the gas valve. The igniter is a lot cheaper than the valve, so I replaced it first, but it did not fix the problem. Replaced the gas valve assy and it now heats up as quickly as when it was new. Seems like a weird design.

After I bought it, I found a better description of how to determine if it is the igniter or the valve that is bad. Search the online repair sites for troubleshooting info.
