I used another tool first

then I bought this and fared better with this than I did with the other tool."

Ok, you ready? I'm 48 yrs. old, a girl, and have NEVER cut finish trim in my life!!!!!! I wanted to add a piece of DIY crown to make Craftman Style Laundry cabinet, and here it is on the first try! My miter was almost 46 degrees! Now if I would have cut this at a true 45, I would've been caulking and spackling this stuff like mad! Now you may not like my choice of style, but at least you know that this crazy tool is worth EVERY penny!

Slick As Hell !!

If you do or are going to do trim work of any kind, if you are even THINKING about doing trim work, crown, base, door WHATEVER..... get this tool. Even makes an idiot like me LOOK like I know what I'm doing !

this is a nice tool , it figures out the correct angle need for miter joints , it takes out the old (2) part (2) tool method , i recently saw a contractor use the larger version to make a unknown angle miter cut , with no effort , the miter was correct no gaps , no need to caulk the joint excessively , some times these unknown miter cuts take a few trips back n forth to the saw , if you actually have a conscious about your work , even if it is getting painted , some guys would probably laugh @ someone using this protractor , but really wishing they had 1 ! unless you have a laser protractor installed in your eye , doing crown moulding can be a little tricky , that is if a caulking tube isnt one of your most used tools

Must Have this!!

If you are doing any molding/crown work you must have this tool. Just because you think it is a 90 doesn't mean a thing. Ask yourself "Was this place built by humans?" If the answer is Yes - then you need to check the angle and cut accordingly. That is how you wind up with tight cuts. You find out it really is 88 degrees instead of 90 and you cut accordingly and get a tight fit. Also, for odd angles (like doing a kickboard down the stairway - you will never get the angle without something like this (or re-taking Geometry). First time you catch an off angle, cut it accordingly and see that tight joint - you will thank me
