Overall, this machine is fantastic and it's definitely earned its place as one of the go-to tools in my shop. The motor is smooth and quiet, and clearly very powerful and high quality. Aside from the occasional removal of leather dust, this machine is very low maintenance. I would highly recommend anyone who produces leather pieces regularly to invest in a Power Burnisher. The time I save, and the quality of work it helps me produce has made this tool indispensable.
