I have been use'ing mine for about 3 years now and it does a great job,
though i only have cut aluminum shafts it is capable to do carbon shafts as well . I have been happy with it.
Best 20.00 bucks i've spent..
I do not have it setup on a jig ,a tape measure and fineline marker work just fine.
So whatever you decide good luck and have fun.
