This is one of my biggest complaints with Festool. I worked in a shop that had several CT Mini's and now I have one at home. They all have the same problem with the outlet losing it's grip. The one I have at home hasn't seen very much use and is already loose. The problem is in the design of the outlet. The Festool outlet is only a single swipe. That means that each blade of the plug is held in with one spring loaded blade (a swipe) in the outlet. Outlets like this are the lowest quality available. Better quality outlets will have two and even three swipes.
