I've used one for a couple years, they are great, quick. I use the water cooled coil. Cycle time on 223 and 6.5 CM is about 2.0 to 2.5 seconds per piece. I made a trap door type base to set the unit on, drop brass in coil and push the start button, when light goes off, drop the brass out the bottom into a tray. It's actually the fastest step in my reloading process.
