I would give it a 4 out of 5 rating. I believe it will improve my productivity and accuracy . The product came well packaged inside a plastic tube with end caps and two zippy lock bags of parts. This made easier to unpack. No instructions but intuitive to assemble. The 8 ft pro pack comes with plastic arms that formed to be flush with the bottom of the jig. They did sell them as an accessory and I would have ordered but could no longer find. They may not come with 8 ft anymore either. I have several other projects it will be handy. The other side of the jig has a center finding scale.
