My equipment undergoing electrical overload due to storms and despite a multi-outlet (Belkin) supposedly para lightning, but not at all effective (the devices have "Cramer": TV, Box and multi-media disc). Buying a new decision seemed excessive. So, I opted for this small outlet, a surge protector, my dear Strip. I'll see the next electrical problem ...
The interesting point is the LED indicating "active operation", at least it's a way to know if the product is to change as already "activated".
