Query: Unbelievable!

I purchased this saw as a bit of an unknown. Seemed that it might be useful IF it worked as expected. No way - it's MUCH MUCH better than I could have imagined. First cuts through 1.25 inch thick wall tubing. No fuss, no effort, NO SPARKS. Smooth cuts with few or no burrs. Why haven't I had one for 10 years? Oh well, live and learn.BTW, I am using this with the V18 Lithium batteries. It was designed for NiCads, but is forward compatible.
