I use these in a plug in and forget scenario taking signal to and from racks and patchbays in the studio.
Despite being cheap, the molded connectors are ok (no option to maintain of course, but these almost never get moved from their sockets, and the cables are also supported in the back of the rack for strain relief).
The cable itself is reasonably flexible and not too prone to kinking so it's easy when I need to roll the racks out from time to time.
Sound quality is fine, they add no discernable noise or degradation to the line level balanced signals.
Despite being super economical, they perform perfectly well in this scenario.
