PowerCube ReWirable - Modular Extension with Customizable Plug for Global Use

Seems to work well, the plugs have a plastic locking feature, which put my mind at ease about pulling this off the wall, but leaving the plug in. The included cable is only a 0.5 m long one, but I have plenty of longer ones, and very few this short, so, I don't mind this much. The lack of a plastic mounting plate was a bit of a damper, but I suppose this is meant to come with you to places, and stay in one place less.

Function color-coding is king

I wish you kept the color-coding of the cube's function - this for me was a great idea. Pity, you've deviated.
