It is great. Same diameter as the saw lock on my Dewalt so I can push the lock to engage it. Writes very well. Very sturdy all metal.
Cons
Has a tendency to come unscrewed in the pocket. Which can be a problem I you lose the small spring.
Also I dont know what the replacement cartridge is, so I will have to email the Captain.
