I bought these patch cables because I wanted to avoid big bulky connectors, so I could maximize the number of pedals on my pedalboard (I assume that's everyone's motivation for getting these).
After more than two years of use, there haven't been any issues at all, even after about 3 re-wires of the board. Quality has been excellent, I have always used an isolated power supply with them and have not really taken particular care in my cable runs, but I have found no additional noise coming from my pedalboard (I also use a humbucker pickup so YMMV with single coils & daisy chained pedals). I also picked up an EBS flat patch cable recently because they were the only thing I could find locally and honestly the build quality is very similar, with these being about twice as affordable. I could not tell the difference with sound, noise or anything of the sort.
If you're looking for your first pedalboard cables, figure out the length you need for your cable runs and get some of these! Can't go wrong. Excellent product.
