More by chance "stumbled" I about ProCube and must say: horny does not work! On a narrow area a double charging solution on top of that looks super chic and much more flexible (eg with regard to the uncomplicated charging AA batteries) than it ever could be an original sen.
My deepest (and even technical) respect to the company Hähnle, that's for a product that you like to around 60.- goes over the bar.
