I bought this to use in my RV-7A which has very little room in the cockpit and so the controller for my wife's Bose headset is always getting in her way. This seems to be a well made product but it does fit the controller a little more tightly than I would like. We take the headset out of the plane between flights and the controller was just too hard to get in and out of the holder for my likes. The tightness was remedied in less than 2 minutes by sanding the gripping edges lightly with sand paper. Have not mounted the holder in the plane yet but suspect the adhesive provided will prove adequate and if not I plan to mount the holder semi-permanently with silicone glue or maybe with industrial strength sticky back Velcro (yes- that's a thing and the adhesive on that stuff is amazing!).
