I used to love her but I had to kill her, 3 times. My autosiphon that is. When you've had the crappy seals they use leak air on 3 different autosiphons, well...you kill them. I also don't like cardboard beer either. Ya know, they sure could improve on those if they made them out of something thicker that could take a better seal than that crappy plastic outer tube they use.
I now just use a 1/2 inch racking cane and start the siphon the manual way.
As easy as they are to use- if you don't know how to start a manual siphon, when your autosiphon starts to leak air, then you shouldn't be homebrewing. I regret wasting money on the things.
