Thanks for the tip! I just exchanged my siphon for the Mini version in my order and got the clip as well.
But will it be long enough for the 12l carboy? It says that the retracted length is 34cm while the height of the 12l carboy is 40cm. I also use 1 gallon carboys but it would suck if I couldn't use it for the 12l one.
That is the short one. Cancel the order and get the small diameter auto siphon that is about 58 centimeters.
