I needed some short XLR patch cables for my rack and din't want to make any myself (I am obviously getting lazy as I am getting older) so I took a punt and bought these.
So we are looming at around 2¤ per cable, My Neutrik plugs (when I do build my own cables) alone cost most than that. The plugs are OK, I have had issues with the barrels twisting and the locking pins not aligning which is a pain, but one in place I get the feeling that they are happy if they are not used.
For applications where the plugs are going in and out all of the time, I would not give these a very ling lifespan, but for permanent installations they are fine and do the job.
So if you are desperate and feeling a little pokey on the money side of things they are OK, but if your gig relies on them then go for something a little more substantial (or make them yourselves).
....... they they are OK .... that's about it.
