A long time to draw Super Easy installation since tiller, so of course, are more than clear! Very good vibration damping. You have not even afraid to tear broken these things, they are much softer and more elastic than most competing products.
But fans have been perfectly pure play / loose dangle. 20pcs for ~ 6 is also an absolute Wahnsinnspreis. Small gimmick: An illustrated manual and a rather classy-sounding box with foam insert, so that the good things take no damage)
