I'm fascinated by this device! So small and so useful! What I like about it, is that it is made to operate in a vibrating environment. And "the DF50 Series board-to-wire connector is designed with blade type contacts attached to a thick, resilient housing wall that is resistant to cracking or deformation normally caused by wrenching forces during assembly" sounds really cool) I use to crack 2-3 connectors days ago. I hope this won't happen to this one as they promise..
