Enough said? If not, this tool works exactly as advertised and no way can you make your work easier and more accurate.  and if you can email me as to how.  tkae the time to read the directions and then you will be using this tool even when you don't need it.  I broke mine out at the job and was the envy of the job.  as well as very popular (loaning it out). it will figure any angle out for you. and if you are like me and prefer quality miters as opposed to coping your joints.  then this is the tool for you
