Need a heavy duty extension cord for one of our bathrooms. One that can run the fan in the summer to get rid of the moisture as my husband thinks the shower should double as a sauna. And in winter, run a portable heater to warm up quickly. The cable we used has a standard head that sticks out too far and gets in the way. The cable itself is stiff and this also caused difficulties. This new flat head flex cable is exactly what I was looking for. I can't say how durable the product is yet as I've only been using it for a few days. So far, so good.
