The bottling process is delicate in that you don't want to stir up the trub at the bottom while you are siphoning to the bottling bucket. This thing is sweet. It holds the auto-siphon perfectly still while you move the beer to the bucket and you can walk away to do other stuff. The trick is to lower it just enough that it avoids sucking up the sediment at the bottom of the carboy.

Very cool. It goes great with my vintage 1970's red and blue Craftsman screwdriver set in my work shop. Lots of compliments from friends and family.
