I can see the tubing...there's about 1.5" of clear hose connecting the spigot to the fill wand. my spigots are the exact same diameter as the bottling wand...I'd never be able to jam it up inside like Revvy's pictures.
either way the end result is that it works hella better than 5" of hose like most books recommend. it also slows the filling of the bottles a little since you have less distance for gravity to affect beer flow by speeding it up. Controlling the flow of filling is important...too fast and you could whip air into some bottles...or simply make a HUGE mess.
