Just got mine today. Plan on using tomorrow. From all I've read and heard, a lot of these first time use horror stories are from people not following the instructions. Cold bottles, cold bottles, low psi ( 2psi), use a pint glass for your first fill until you've got it rolling past the foam up--- remember your beer line is also WARM and this helps cool it down too, cold bottles, LOW psi, AND DONT BLEED THE CO2 OFF THE HEADSPACE OF YOUR KEG BEFORE YOU USE!
FYI: mine came with 10 feet of 3/16 liquid line. Not sure if th early sales were coming with shorter lines. So, this 10' liquid line in the box could be a response from NB to correct some problems.
I'll be sure to post tomorrow!
Ps.. Here's a link to a YouTube video. This dude posted 2 hater videos on YouTube and swore to ship it back before he finally posted this one praising its glory and owning up to causing the foam himself:
