So what was the end result? Did they send you longer cords?
I have exactly the same cable except 50Ft but unfortunately I could only get it in black and yellow. I have managed to hide it well I generally use it as power from the wall and most of it ends up under the table
I honestly don't remember what came about it. They did not send me longer cords. I just kept the ones they sent me. They work fine.
I think they sent me a small coupon discount code or something like that towards my next purchase.
