I have this power strip for some time in operation and it works flawlessly. They need not fear, because it also looks very good also. The existing lights are clearly visible, but very discreet and therefore not at all disturbing. The overvoltage protection gives me the exciting sense of additional security because I have especially expensive equipment such as television etc connected. Whether this in the case of Blitzeischlages really helps, I would not really only find out :) Overall I can only recommend this product.
