Don't know if anyone has tried Panasonic, but we've kinda gotten addicted. The 15.6 volt kit is personal favorite. VERY expensive, but hands down the best conduit cutting (and safest) made. With all attic/crawl/dark work we do it's great. New 3.5 hour battery is big improvement over 3 hour. P.S. much too expensive blade wise for IMC or rigid.
