At first glance they appear to be a good and reliable power strip. what they basically are. But that's all they are. Housing/Insulation - Straight Plastic. At a temperature below 30 degrees, it is almost impossible to work with them. They were once used for Christmas lights. FORGET IT! In snowy weather, the case gets hard and the cables tend to stay in shape until you warm them up. Only when they are WELL warmed up can you roll them up again. But they work great, stand up to outdoor use (in the snow) and are reasonably priced. So 3 stars. It's not a bad extension, but they don't have anything special or better than average.
