man people love that tool. i guess its kind of cool, but my cheapish chainwhip and lockring tool have been more than adequate for my needs. as far as the 15 mm wrench, its a nice add on but it isn't like i would ever carry that thing in my bag so it isn't much of a selling point for me. *shrug*
yeah, for that price it really only makes sense if you're going to the track and don't want to have to carry all your tools in your bag with you.
but i know i definitly wouldn't carry a $130 tool in my bag to get stolen or broken... and if i'm leaving it at my house on my tool bench what's the point? i already have bombproof versions of all those tools.
seriously, leave that tool to the people who really feel they need it (or spend the insane amount of money on it, i don't give a schit).
