Saker Miter Saw Protractor|7-Inch Aluminum Protractor Angle Finder Featuring Precision Laser-Inside & Outside Miter Angle Finder for Carpenters, Plumbers and All Building Trades (Black)

Excellent product, very well built ! I use it all the time when matching angles on staircases and wall corners to get tight fitting trim every time !

For what I needed and how I use it it's perfect:I do NOT use it for measuring miters for "inside" corner cuts. That's too frustrating to me and I do those by the "coping" method.I DO use it to check "outside" corners when mitering trim, checking the calibration on my miter saw, and for measuring trim angles that are obviously not 90 degrees or close to it.Some reviewers have been displeased with the accuracy so I added a photo to my review of checking it against the standard of my nearly indestructible and perfectly accurate quick-square. As you can see on the "inner measure" with the white arrow it is dead-on. If you want to use this for mitering "inside" cuts then be sure to read the instructions completely.Last, this is made from high quality metal. It is milled and powder-coated very well, the markings are nice and clear, and the "play" on the movement is nice and still so you can't easily move and lose your measure. It has a hex screw on the back for adjusting the stiffness.

Great tool to determine miter saw angles on trim. Easy to use and very functional.

Works good little complex for bigeners

Very well built. I was doing a big crown molding job, and this came in priceless for figuring out the angles to get the perfect cut.

So far it has proven to very accurate. Just wish it would have been delivered to the house instead of the post office

I haven’t used it, but it seems very well machine and very easy to read. Looking forward to using.

Works great save my life
