The "Pro snake Patch Angled Jack 0,15 m" is about the cheapest little patch lead you will find but the cheap price is not an indication of quality, these are a great little patch lead and very high quality.
I run a fairly long pedal chain in my rig, a dozen pedals so I'm using eleven of these patch leads and with all pedal off I don't have any noise, compared to running a guitar straight into my amp I'm not noticing any drop or losses so I have no complaints.
The metal angled jacks offer plenty of cable protection but these patch leads also have a piece of heat-shrink tubing at each end of the cable which covers the solder joints and adds further protection and stability, these are well made and durable patch leads.
They seem to be the perfect length, not too long and not too short, just right, I'm running a mixture of pedals in two rows of six with inputs and outputs in various positions on the back and sides and the 15cm leads are just long enough for every joint.
If your joining two identical pedals with sockets on the side the angled jacks allow you to couple them with just 40mm between pedals so they are a really neat solution.
When I started using pedals I was just using the cheap multi coloured leads with moulded plastic covered jacks that often come free with pedals, as a result my pedal chain crackled and hissed constantly, after that I "upgraded" with Planet Wave patch leads which was a huge mistake, the jacks fell apart and jammed in the sockets, these pro snake patch leads are a much better solution, very quiet and good quality jacks, highly recommended
