There is so much difference in cable quality that I have a hard time buying cables that I can't inspect first. I purchased these based on online comments and I was quite surprised at the quality of these cables. The cable covering is soft and pliable. All of the connections tested "good." I will be using these on my traveling keyboard rig.
PROS: Durable and soft rubber coating. Molded strain relief.
When it comes to data cables, a cable is a cable. Not only is this one a great price, but it actually feels as durable as the expensive cable I was replacing from guitar center. I use MIDI to switch my effects and channel setting on my guitar amp, so this cable goes from my MIDI footswitch to my effects unit. I've had probably 20 band practices and 3 shows and no problems so far! Nothing lasts forever, but something tells me this thing will hold out just as long as the overpriced cables I would get at a brick & mortar store, without being a pain on my wallet.
