I like the size selection. I'm a beginner so don't take my review as I absolutely know what I'm talking about. I broke every little piece. I did this through a job with them and it worked fine. But the next broken. I dropped one and it broke too. I'm not sure if the feed rate was too high or what. One broke into a knot in the woods. In general I am satisfied with the purchase. Overall it was a cheap set with lots of bits. Allowed me to practice running multiple toolpaths for one job.
