Let's start off with what the company has to say about it...
I love this little tool. I couldn't get the nut back onto my son's bike. It was IMPOSSIBLE! It seemed like I didn't have just the right size wrench - so frustrating! Then this little guy got here! It took me a second to figure out which one was the right size, but sure enough it was on there. My biggest issue was having the strength to turn it... the nut had rusted or something.
But with a little umph I got it off, and got his tire and chain fixed! WOOT! I wouldn't have been able to do it otherwise. My biggest issue was that because it's a flat piece of metal with the wrench holes cut into it, it can feel a little sharp. Not sharp enough to cut you, but if you have to put some umph behind the wrench it can be a little uncomfortable. Perhaps on their next design they can design a moveable comfort sleeve for the rest of the wrench. Just a thought.
Other than that, I loved it. It worked perfectly and did exactly what I needed it to. If you need a bike wrench, this is the one to get.
