"Well made / no issues with them and I received 12 in my package... bonus bag."

"Except for one that looked like it was sized for 7/16" threads and not the `1/4" threads I needed."
"Delivered as advertised, served its purpose perfectly."
"I have a goldwing with side vents that had a chrome round knob to tighten the angle to get airflow into your crotch area,, I could never get the round knob to tighten enough and when I was on the highway one of my vent wings blew open and spidered ( since they are plexiglass) needless to say that is when I hunted up these, love them, locks my vent in place right now and I do not mis the chrome."
"They're quite small, but solid units."
