I own several of these and have had no issues so far. I use them to connect gear in my studio, so they mostly stay connected at all times.
They do feel a little cheap but I can't really complain at this price point.
I've had issues with the coloured rubber bands snapping off on more than one cable; seems little the rubber had dried up. Nothing a little glue couldn't fix though, and the cables are marked with (small) numbers as well so no risk of getting the cables mixed up it this happens.
I would have preferred if the colours were a bit different though; two cables are different shades of red, and two are black and dark grey respectively, which makes it hard to tell them apart in poorly lit conditions. The colour coding on the sssnake FSP cables are better, in my opinion.
Still, highly recommended!
