I had gotten one of these a while back because it was the same price for 1 draw as 2 biners.
I really dislike the webbing. It is much more floppy than a normal (nylon) draw material and twists around quite a bit. I prefer to clip a tripled 60cm sling than this.
Biners are great though.
If you are just sport climbing I don't see a real reason not to just get a less limp wider draw.
