This knob is a finger saver. For years the knob for my Jeep YJ air conditioner has been missing. I have suffered every time that I had to increase or decrease the fan speed. All I had to manipulate, was a short hard metal rod with a flat on one side. Needless to say it was an uncomfortable situation, because controlling fan speed left small indentations on my thumb and forefinger. If I was traveling down a bumpy road, all bets were off. There were several harrowing moments where blood was almost spilled. Now that is all behind me. This knob has opened new worlds of digit comfort for me. I no longer fear the finger pain horror that I had become accustomed to. This knob is a nice tapered affair which is easy on the fingers. It exactly matches the original knob. It even had the emblem of a fan imprinted on its face. Now I will know exactly what I am doing when I turn that knob. Thank you Ebay for asking me to rate this knob.
