These cutters are a steal! I was going to give them 4 stars because they are nowhere near as good as my Freud routers that I have, but I am a beginner in carpentry and this is a great starter bit set to get started using my router to get used to it while giving me versatility to be affordable. I've been using this set for about 2 months and all the bits I've used so far have worked great. I bought a set to see which attachments I would use the most and replaced them individually with better quality attachments.
