You are going to trade me yours, for my modded kegger.

 

the guys at hughes said if you call or email them they give free shipping with the airgap. i didnt bother though i just ordered it !

 

You think they'll also throw in a manufacturers defect like they have for others for free as well? And maybe, if we're lucky, so crappy customer service? That would be great!
