I recently came across this site and plan to use them myself very soon. I think these can make electrical installations very easy and clean. Supposed to be vibration proof also. I would like hearing from anyone who has used them.

I used them few times. Electrically they are good, but very bulky and unjustifiably expensive. I use primarily metal butt connector crimped or soldered with dual or triple wall shrinkable tubing. Most of my electrical staff I buy from Delcity, great service and low cost.
