Great and quick
Easy to install, simply push in the rubber protection on the spark plug wire with a little dish soap liquid to make it slip in easy, insert the wire and turn clockwise until secure, put back two rubber seals. Done! works great!

feels like it's good quality
Haven't installed yet, feels like it's good quality. A lot smaller than I imagined, each straight is about 1" each, so including the elbow, I would say it is 2.5 - 3 inches long. Has connection for standard spark plug, not the spark plug with the screw at the top.
