Familiarity: I've put it through the wringer
Got this tool last week for my commuter bike and literally 24 hrs later it saved my "a**"... the bolt on my seat post became loose at about 1/3 way home. (about 8 miles left.) i thought i was going to be able to tough it out but the position of the seat was literally goin' up my a**.
I remembered I had this tool in my converted waterbottle tool kit and pulled over. literally within 5 mins I had my seat back to normal and was able to ride home!
this tool is very useful and compact, it's got all the items you need. nothing to think about, just get it!
