I just ordered six 25 footers a few days ago just to have for live shows and stuff where cables get beat up more often, but I'll probably use them a few times for recording live, since I have a limited amount of nice home made cables. I figure these are cheaper than even making your own, so for live stuff in bad sounding bars you can't go wrong anyways. Plus, I like the different colors, sadly I'm not very organized so I'm sure it will help mixing live when I can see where things are coming from. My home made ones are currently all yellow.
Frankly, I'm sure they are the same as any cheap cables, workable, but not pro by any means. You get what you pay for. They probably compare to like... Hosa, Horizon, Groove Plugs, stuff like that. Musicians Friend has 25' for $2.99 right now, but those cables are cheaper than cheap and I hate doing business with them.
