Well they are very good. At this price you get what you pay for and they work. Remember that the following will happen to your bits: 1-Blue color will begin to peel after 2-3 cuts 2-Steel shanks tend to ignite a dark color after 10-15 cuts. 3-You're always snapping plywood and often splitting hardwood unless you work VERY slowly. Given the above, they get the job done for a beginner, not a pro.
