When I tried these replacement pigtails for my INDUSTRIAL electrical setup, i was very impressed with their quality. They fit perfectly and have worked seamlessly with my appliances. The price is very affordable for a pack of 2 and the 6 ft length is convenient. The only drawback is the lack of variety in length options. Overall, I highly recommend these pigtails for anyone in need of reliable and affordable wiring and connecting solutions for their industrial and scientific equipment..
