    I used this product for the first time today. My first piece to cut was perfect and the tool was a breeze to use. I’ll write back at the end of the project to let you know how it holds up, but so far, it’s perfect and easy to use.

    When the item finally arrived it was pretty much as described. We are still testing it to suit our needs.

    Such innovation. Measures from inside the 45 degree angle short length (as is necessary).

    Haven’t had a chance to use it yet, but it arrived so fast I wondered if you had read my mind that I WAS going to order it.

    A little different than the one I saw on the video with the two little nails. This one seems to be a plane one.
