*by W***K on 24 October 2022*

A sturdy extension cord made with rugged materials. This is a high quality cord, much better than other ones priced higher. I haven't yet been able to confirm the claim of cold weather flexibility, but I am confident that it will surpass expectations. Excellent value.
