Thanks for the info. This is exactly what I asked for. Real people with actual experience with the tool.you know i just pulled out my buffer to do a quick polish on my boat. this video really exaggerates the sound. both sound really loud in the video. nothing like in person. at speeds that we would normally buff at my makita cordless drill is louder than the 3403. now with this thread making me take notice and just trying it its prob one of the quietest buffers i have used. running it typically at 1400-2000.
