Strengths: Easy to use. Most common sizes on the Y. Significantly easier and more useful than a standard alan wrench.
Weaknesses: Because of tapering, it's possible to snap the 4mm tool head (which I just did) easier than you'd think. Also, it's possible to have the tool walk out of an alan head, so if you're using lots of force, use a straight sided alan tool.
Great product for hard to reach places: tapered alan head.
