You used to get one of these in the box with Behringer gear, but Thomann didn't even bother to include one with my recent Kobol expander purchase, meaning I had to source my own before I could use it... thanks Thomann :( The problem with them is together with the 'wall-wart' they make the power supply huge and mechanically unstable (to the extent i wouldn't trust the thing) i.e. the last thing you really need if you're pugging stuff in behind a rack. Worse thing is that the PSU's Behringer ship have interchangeable clip on face plates to adapt to US, EU, UK, india mains outlets. If they threw in the appropriate region adapter there'd be no use for this, and less plastic in the landfill, less grumpy customers. Please can Behringer and Thomann have a chat about this and improve service to the non-mainland Europe customers!
