In my book, light is always easier, and that's one thing that makes the Kapex stand out. But it is also faster, because the double-sided laser is user-adjustable, making it spot-on, whether you like to cut right on the line or right to the center of the line. And the engineering is smarter than any other portable saw I've used - there's zero deflection, even on acute, compound angles cuts.Gary Katz, Nationally Recognized Author & Trim Carpenter
