Patrick Mulliganwrote a review of Topeak Alien III Multi Tool on March 3, 2015
Familiarity: I've put it through the wringer
I upgraded from the original alien (which I gave to someone in need on a long ride) and haven't looked back. This is not a minimalist tool, I ride with a crank bros 19 when I'm simply out for a quick ride. However, with this thing, I put a boot and a couple of quicklinks for my chain in the case for long rides. You really wouldn't need anything else if you're suffering from a mechanical beyond a pump and a tube. That said, I've never had a mechanical (or seen someone else's) that couldn't be fixed by this thing. I've even broken it out when folks don't have the appropriate tool in their kit at the cars.
