The power plug / surge protector is working at least as far as the plug function! Power is there, and the green light also lights up, the power-on displays. And that's not always the case. I have another surge protection plug in the lamp so was installed that you see them only after the plastic Ummantlung seem. Cheap flat. What's in this product is not the case, and the plug to make a quality impression. He is firmly seated and the connector of the connected device sits just as safely and securely. More I can not testify for now. As for the surge protection I can, and I have hopefully never to say anything, I do not want to let only enter the "real thing" !! But if the want but should still be the case again, then I'll take my product review to the effect complete. So, at first green light and recommended for sale.
