They worked well while they lasted, but after only occasional use one of the wires started separating from the connector. By occasional use, I mean 4-6 times per month for the last nine months. Contrast this with my original Super Nintendo controllers, which I have had for 26 years, and which are still in fine condition. I mention the age and condition of my original controllers to make clear that thee reliability failure of the extension cable isn't a user issue (as I take care of my equipment). Had I known that I would have to buy replacement extension cables just nine months after purchase, I would have gone with a different option.One other note: The item description says these cords are black, but the product photo might make you think perhaps the product strays toward grey (coming closer to the original controller cable color). Trust the product description, not the photo. These cords are straight-up black.Works great. I now have my original SNES up n running againLOVE! I especially love that I can actually sit on my couch and play my SNES on my big screen- rather than needing to lie on the floor as I was due to my cords being too short. Super happy I bought these, they work perfectly!These extension cables work great. I can now comfortably sit on the couch and play my super nintendo without having to reach or worry about dragging my console on the ground when I get into the games I'm playing. For $2, they were worth every penny.I bought these to use with a retro duo console and they work perfectly. They are a simple product, not much more to say, 6ft in length makes the regular controllers couch length, without having the console on the floor.They do what they were designed to do. What else can I sayOne connector has a bad rattle... feels cheep.Great description, fast shipping, and good product! Would purchase from seller again!Preis und Leistung entsprechen der Angaben,die Ware wurde zügig geliefert und schon öfters verwendet.Volle Empfehlung auch bei Anschluss an einen Verteiler.
