I bought my first sssnake blue cable around a year ago, and it's still there! I even tied 2 of them together (with tide-rips) for my Tommics!
At first when buying the cable i estimated it would last for about 6 months or something, because the price was this low.
a year later i'm still using them, and i'm having not a single complaint. The connectors are pretty strong, the cable still sends without any fails, and of course: the color didn't fails.
I have to take a note though. I've been using it in my home studio only until now. I'm not really looking after them, but they don't suffer any "live"-conditions, like beer, people walking on them, misfortunes etc. etc.
Still, i'd recommend it for people who want an extra spare cable, want to use it at home, and for rehearsals. They're better than you'd think at first (price)look.
