I tried it on a friend's recommendation. Arrived well packaged in a reusable plastic case, the build quality is excellent at first glance. Good heaviness. I like that the pilot jet can be replaced with a hex head screw. It cut through 3/16 aluminum plates with ease, but I'll admit that since it looks so good I'll wait a while before trying it on steel. I just like keeping the tools pristine for a while. I tried it on plywood and it made a very accurate cut despite the plywood thickness being limited to 1/2 inch max. I will most likely buy another nozzle or two in different sizes as the need arises.
