I do professional knife, and tool sharpening as a side hustle. I had never sharpened circular saw blades beforeI but after watching a few YouTube videos of others using this tool, I saw a opportunity to add saw blade sharpening to my services and be able to make the tool pay for itself in a short period. I already contacted a few local carpenters and they are excited to hear the don't have to send blades out for a week or two to get them sharpened. The tool did arrive with some minor damage to the metal cap on the motor housing that I was able to easily fix, no damage to the motor. The cup washer that holds down the saw blade was about 1/8 too short to contact the saw blade. Added a couple rubber feet to the washer and I think it's even better now. The radial runout on the diamond sharpening disc was measured at 0.020 (twenty thousandths) which I felt was a little excessive. It does seem to have gotten better with a little use. Although in a different time zone, the customer care dept was very responsive to my emails, it took about 18 hours to respond. Take lot of pictures of the box before and after opening, contents of the box, and any damage you find. You will also need to have pictures of the labels on the box, so don't throw it away. Very important to give the saw blade a good soaking in laundry detergent or some Simple Green Purple cleaning solution BEFORE you start to sharpen to remove all the pine pitch and sap on the blade teeth. The pitch and sap will clog up the diamond blade very quickly if you don't. Watch some of the YouTube videos on how to set the tool up for blade sharpening. Another tip is to buy yourself a digital angle gauge to check the level of the motor (see photo), blade, and blade platform, they should all be the same, or very close. I took a 10\", 60 tooth blade that was just burning into wood when you tired to cut with it, it would smoke as soon as it got into the wood. Spent about 15-20 minutes getting the blade set up and
