I thought about buying the Area 419 kit but after I saw a friend use the Satern funnels I bought some and never looked back. They are caliber specific and I have never lost powder around the edges, are made of aluminum so I have never had any static, and have brass at the bottom so it makes them bottom heavy and they stay on the brass mouth. I now have one for 223, 6.5mm, .270 and 30 caliber. These are the calibers I shoot the most and if I ever buy another caliber I'll just buy its own funnel. Totally worth it in my book. Good compromise for price and functionality.
