Amazing quality for the price. I only used the longest. I was busy and burned out a H*****F******** router I had for a few years. I realized it was old and that was the turning point. I bought a Ry*** router and burned it in about 10 minutes. Picked this up and got a Rid*** router and it did what I was trying to do with ease. At first I thought they weren't up to the task, but those were just the routers I was using. Make sure you have a good enough router or have the ability to get a replacement as this tool will weed out the weak ones.
