I use the Lee Universal to decap the longer brass which I couldn't decap on my drill press with a nail. When I first started using it, I broke the decappping pin in less than 30 cases (user error); therefore, I would recommend you order an additonal pin for backup.
Once I replaced the pin, I've had zero problems with the next couple of thousand+ cases. You will need to be careful with small mouth cases such as .223 and watch out for berdan primed cases (another reason to have a spare pin/rod).
A lack of planning on your part does not necessarily constitute an emergency on my part.
