I was in need of some particular lengths of Doepfer cables for my portable Eurorack and these fit the bill perfectly!
I have a tool/camera case converted for portable Eurorack use and needed to take it on a flight. As such I didn't want to be taking all my 3 ft leads and wanted to keep cable clutter down for demonstration at my destination.
These were perfect. I know some modules don't play nice with Doepfers choice of jack but personally I have not had a single issue. These are low cost and low feature - until you need that exact length and then they are just perfect!
Pros - exactly what I needed when I needed them. I haven't needed them for 7 years but I did this year and they were perfect! Good value for money. Consider also a dense patch - the Doepfer cables have a very narrow 'barrel' so you can get at your modules knobs without too much clutter. Many higher cost 'braided' cables have a lot of plastic around the shaft and can make patching two close together a mechanical strain on the jack sockets - not so with these.
Cons - Some modules dont seem to lock the jack end in fully and can lead (sic) to a feeling that the cable will fall out from the module. I don't know if this was a thing with initial Doepfer cables or with the modules themselves but I did not have an issue at all with these cables.
As soon as I need more I will be buying these cables instantly. I have a number of Doepfer cables I bought with my initial entry into Eurorack 7 years ago and not had one go bad yet. I have bought fancy, multi coloured cables from other manufacturers that arrived DOA.
