If you have many pedals on your board, these are a great option. It's the second time I order a few of these, and now my pedalboard is almost exclusively connected by them, with only a couple others of custom length. I was impressed with how much cleaner my guitar signal was after I replaced a couple of my old patch cables with these, so I decided to order more.
These cables are very low profile - they will tidy up your pedalboard and free THAT space for another pedal. Also, I'm very happy with the quality of their performance so far, as having many pedals on the board can give rise to all sorts of problems and these cables have made my life easier in that regard.
As I already mentioned in the review of the 5cm version, the only thing keeping from having only Rockboard cables is that sometimes the sizes available are not perfect for a specific spot, because I would definitely buy sizes in between (like 3 or 7cm). However, I understand this may not be practical and that the sizes available are already diverse (5cm, 10cm, 15cm...). Overall great purchase.
