Product review (3 stars): Not ideal for older machines.
Ordered this specifically because, on my dryer, the shoulders of newer bulbs are too high to screw in with the rubber seal in place.  Why a company would redesign a  light bulb is fodder for a longer conversation.  I was disappointed to find that this appears to be the new model.  It works, but had to leave the gasket off to get it in.  Worth noting.
