The blades arrived well packaged and on time. I worked on one of these for about two hours today, cutting 1/2" hard maple, and it did a very good job. I think I noticed a slight slowdown in cutting speed towards the end of the cycle, but that's for sure probably because of what to expect there were no noticeable bumps in the welds and the blade moved smoothly and precisely IMHO these are good blades at a reasonable price.
