Very good product purchased to replace another of the same brand that took the water following an air conditioning problem. LoL. with four plugs and four corrugated protected it is ideal for the use I have. I live in the countryside, although at some kilometers from nuclear power plants, I am subject to a lot of small cuts, especially during storms. I am therefore obliged to protect all my electronic equipment, computers, boxing, boxes, telephone, etc ... So it suits me perfectly. jr
