I have them and am very happy with the quality. I used to take them on and off for long trips but no longer bother because my range does not appear affected nor can I discern wind noise (unless I attach something to them). I am always very careful with the torque and placement because I do not want to damage the glass. No idea about third party ones but in my experience it would be difficult to better these Tesla ones. I have heard of whistles from the track in one third party product but that is hearsay.
