Has this router bit been modified or changed since the bad review in 2012 ?

We have not made any changes to the Trex Router Bit. These are the instructions for routing: Instructions to Route Select, Enhance, Transcend, Accents, Brasilia, and Origins 1.On the end of a test sample, measure and make a reference mark ½” from the bottom of the board. 2.With the bit in the router, measure ½” from the router base to the center of the flute. Tighten bit. Check with router manufacturer for proper bit placement into collet. 3.Make a test pass on the sample with the face of the board down. Observe the reference mark and the center of the router bit path. Adjust the height of the router until the center of the groove is aligned with the reference mark. Note: the groove will offset towards the back of the board. Please be sure to route boards with face of the board down. Thanks, Debbie, Trex Customer Experience Team
