I wish the Ducky was built as well as these things, I have noisy Cherry Blue switches which I love but I don't like the feel of them bottoming out, these solved that and feel great!  I used a yellow butt connector for wires to push them down to the base of the keys, out of maybe 200 I installed (2 different boards) maybe 3 of them cracked going on so watch for that.  The Ducky on the other hand, not all the LEDs work but otherwise it's great.
