  • Great little tool!

    Get the best of all worlds in one tool, neatest feature is the "tape measure hook slot" close enough to the blade that you don't lose your line while making long cuts. Even popped a chalk line to see how much deviation there was, not a lot, within a 1/16 inch over 8 foot board. As always, the more you use a tool, the better you "should" get at it! lol

  • An invaluable tool when cutting angles wotj a mitre saw

    I could not say more or better of substance than New England Yankee who gives this product five stars. I agree with everything New England Yankee has said. I wish the instructional and support material for this product were more substantial than it is. I was going to give this product four stars, but New England Yankee persuaded me to give it five.
