I really like the ruler. I have it in my KeySmart with my keys and all the other tools I have bought. I am always looking for a ruler.
It is a neat tool.
The retraction mechanism works fine, but this unit is worse than garbage. The plastic housing broke free from the surrounding chrome housing within 5 weeks of fairly light use. Lost an access card from work that I now have to explain.
This is a nice item for your keychain. It is well made and very useful.
This product is the best. I use the mini tool everyday.
