Mandolin Truss Rod

First, I would like to compliment Stumac on the speed with which I received my order. Good job.
The truss rod is good quality and as advertised. The instructions were great and easy to understand. The largest problem was jigging up the tapered neck to route the slot down the center. I did note that the rod came out of the anchor lug slightly off center, about .008", but this small flaw caused no problems. I would definitely recommend this product.
