Cheaply made but has strong plugends. I wish the insulation was like more like the heavy duty outside extension. Cords. This cord is still good especially for the price. The male and female ends are high grade plugs it looks like. Just wish they woulda placed a thicker outer insulation over the extension cord but it’s water proof and can be used outside it’s worth buy for long cord for the price

Good Product

Size: 50 FT, Style: 16/3 Extension Cord, Color: Black

I bought this for some Christmas decorations and it worked out well. I probably could have found a cheaper one in a store but it was convenient to buy it online and it arrived quickly. Great for outdoor use and I'm sure it will last a long time.

Very good

Size: 50 FT, Style: 16/3 Extension Cord, Color: Black

Good value for the price. This 50 ft extension cord feels durable and works well both indoors and outdoors. The 16/3 gauge handles my power tools and outdoor equipment without overheating, and the flexibility makes it easy to roll up and store. I also like that it’s ETL listed for added safety. The only reason I’m giving 4 stars instead of 5 is that the cord is a bit stiffer in colder weather than I expected. Other than that, it’s reliable, long enough for most jobs, and a solid buy for everyday use.
