Easy Siphon

[Draughton]

I have one like that and found it doesn't fit into the 5L demis. Should be fine for bigger ones though.

There is a smaller version but I don't know where you can get it here http://www.northernbrewer.com/shop/mini-auto-siphon-3-8.html

I have the 3/8 GandG siphon. It works well but is slow.

I previously bought a keg king one - first one arrived cracked, was replaced with a new one which still didn't work (they were having problems with the ring seals) so they sent me a replacement kit for the seals, but it still didn't work. The GandG one is much better.
