The tool in the OP's link looks a lot like a Topeak Alien II. I have the Topeak and it does good work and works well, there's enough tools included that if you can't fix it, you need a ride anyway. But the Topeak was heavy enough that it got moved to my commuter and replaced with a Topeak Mini 9. The Mini 9 has enough tools to get you out of a jam, the one thing it doesn't have is a chain breaker, and I thought "I haven't used it yet", of course cursing myself to needing a chain breaker on the road (to fix somebody else's bike, and they had a chain breaker, I had the quick link).
