After trying this product, I was severely disappointed by its lack of durability and poor performance... While it may be budget-friendly it ended up costing me more in the long run due to constantly needing to replace it..
Use these on my CNC wood cutting table and they do a great clean precise job. Definitely worth it and I will buy more when they wear out. Used 1mm on birch plywood, walnut and oak and they cut through like butter leaving a finished surface that didn't require sanding. Very happy with the results. This is better than buying a separate large format CO2 laser when some incisions and pockets are required, and just as quick if not faster.
