A couple of weeks ago, we bought a Maggidan's Milker to speed up the farm chores. It's not perfect, but we like it. We still have to fully milk out each teat...about a dozen squeezes on each side. It does speed up the process and the milk handling is cleaner. There is no risk of the doe putting her hoof in the milk, knocking it over or hair and dirt falling in because the container is set further away. It does lose suction from time to time and you can fix that by pumping hot water through it. Hot water is also used to clean it. The does kick at the hose and that can pull it off the teat so we have to pay attention to their movements. I can't say it will be faster for an experience hand milker, but would speed up things for a newbie. It does keep your hands from becoming tired because you only use one and can switch it back and forth. For our $52 investment, we are pleased. You can order and see a movie showing how it works here.
update 4/30: I've been sick and Clint has had an opportunity to use it. He says it is definitely faster for newbies!
