Review: Flexible, well-made extension cord that works indoors or out - This extension cord feels high quality and durable right out of the box. The 6 foot length is perfect for short runs without extra slack. It stays flexible even in colder weather and the insulation feels tough enough for outdoor use. The plug fits securely and the cord does not kink or twist easily. A solid, reliable cord for everyday indoor or outdoor needs.
Review: Sneaky strong and durable - Works perfect, and I can confirm to the strength of this cord as it was buried in the snow and when run over with a snowblower not only did it have the strength to stop my auger, but also didn’t have any tears in the cord once I spent the next 45min untangling its death grip choke hold it had on it. All in all a perfect cord for outdoor use
