I'm a hobby carpenter so can't tell how they differ from other more expensive routers. However, I used an Ogee chisel to profile the edge of the top of a wooden island over 30 feet long. It was sapele which is very hard and breaks easily so I was a bit worried. After some testing on cutoffs to get the router speed right, the bit worked perfectly. He was sharp and precise in everything and seemed to have a lot more life. I was very impressed. I highly recommend these beats.
