Product review (2 stars): Buyer's Remorse
DOES NOT FIT A STANDARD 15.5 GAL KEG!!! Once you finally get this working it does pour beer.  When we first got it home my husband and I had serious trouble securing the tower properly.  I was unable to get any help from the distributor and the manufacturer.  I saw from reviews that other people have that the same issue and the help line response was basically "Yeah, well, it is really tough to get in there.  Watch this video and make sure you're doing it right."  We had been correct the whole time.  My husband and I are not weak people.  I was standing on top of the kegerator pushing down on the tower while he tried to twist it in.  He finally snapped and hacksawed some of the teeth down before it finally twisted in.  We have purchased two 15.5 gallon barrel kegs so far and have to duct tape the door close to keep the seal intact.  Would not purchase anything from EdgeStar again.
