Gets the job done. The fact that they come in different colours is very helpful in keeping track of what goes where and the different length options available all are consistent in colour making it easy to have a system, regardless of the distance between gear.
My one gripe is that I wish they came in 8-packs, with an additional 2 colours. A lot of my gear, like my interface, ADAT expansion unit and mixer, have 8 channels, meaning I have to be a bit inconsistent with what colour maps to which "number".
Another thing is the fact that the colours do not match those of the sssnake TRS patch cables - I would like to match the channel number of where an XLR cable connects to the corresponding colour on the out channel. The exact shade of colour is not the issue but rather the colour itself; I can't recall the exact difference at the time of writing but if I recall correctly the TRS has one bright blue cable while the XLR is a very dark purple, almost black (also making it hard to distinguish from the black cable in poorly lit conditions).
The quality is okay, about what you would expect at this price point.
