Am Anfang war alles gut - hat einwandfrei funktioniert. Mit der Zeit sind die Dummies dann innen ausgeleiert...mit dem Resultat, dass jetzt in meinem Firmenrechner (Surface) ein USB-C Dummy steckt, den ich nicht mehr rausbekomme und jetzt nur noch 1 funktionierenden USB Port habe...hab noch keine Idee, wie ich den USB-Blind-Dummy da wieder rausbekomme...

Easy to handle. Good fit. No complains at all.

the blocker was inserted incorrectly and could not be taken out. The USB port ended up getting damaged and now is unusable. The lindy port seemed to strip and the teeth would not connect to remove the blocker.

The key used to install and remove the USB-C blockers can not remove the blocker from USB-C Ports on Mac Pro's or Mac Mini's. The key doesn't engage with the blocker well enough to pull out the blocker from the tight USB-C ports on apple hardware. Had to remove the blockers from the port with other tools which destroyed the blockers but thankfully did not damage the USB-C ports.The USB-A blockers by Lindy do work well, just not the USB-C ones.

Very useful function provide security at the physical level looks nice easy to use. love it !
