Junk. Avoid.
I thought flat patch cables would be a great way to save space on my pedal board, so I ordered two. It was a mistake.
Unfortunately one didn't work at all and the product is so thin and flimsy that I don't trust the cables to last 5 mins. I threw them both straight in the trash and then bought some higher quality cables (Klotz/Contrik/Vovox).
I probably should have known better. CHF4 is too little for decent cable.
These cables are junk. Avoid.
