Product review (4 stars): Things to know about owning a kegerator
I bought this model in January 2012.  It's worked great so far and we have enjoyed many 1/2 barrels and 1/6 barrels of beer.  As stated in other reviews, don't pay attention to the old reviews.  This is a good, quality kegerator.  FYI - 1/2 barrels are the ones you see at keg parties and are approximately 15.5 gallons and weigh about 160 pounds.  1/6 barrels are the same height as a 1/2 barrel keg, but are much skinnier and are approximately 5.5 gallons and weigh about 60 pounds.

There have been a few items that I wish I would have known about, which would have prevented some frustration along the way.  These may be common sense to some, but as a newbie kegerator owner, I didn't have a clue.  I wanted to share in case other newbies can benefit from my experiences.  I found these things out on my own or after searching the internet.

Faucet
 * Clean it after every keg.  It comes apart, so disassemble it every time and clean it thoroughly.
 * To keep the faucet from sticking, take a small spray bottle of water and spray water up into the faucet.  It sticks after a day or two of not being used and sometimes it's really difficult to pull the faucet.  Something about the sugars in the beer are exposed to air which makes the faucet stick.  Consider getting a Perlic faucet to prevent this.

Cleaning
 * Clean everything after every keg.  This may be a little overkill, but I didn't clean it after three 1/6 barrels of the same beer and I got beer stones in my lines.  Basically, it discolored my beer lines making them look dirty.

CO2 Bottles
 * This comes with a 2.5 lb. bottle, which works just fine.  Probably lasts for 5-6 kegs.  I now have a 5 lb. bottle (which does fit on the back shelf even with the regulator on it) and it's lasted me for seven 1/2 barrels and it's still showing that I have quite a bit left.

Replacement parts
 * This kegerator comes with a few parts, but it's a good idea to get a few more, especially the rubber washers.  Also have some extra beer line on hand, with the proper connectors.
 * The parts it does come with are OK, but I have replaced the faucet and lines with better quality units, which make it even better.

Other notes
 * Let a keg sit at least 2-3 hours after transporting it to let the beer settle, otherwise you could have very foamy beer.  It's even better if you let it sit overnight.
 * You can transport a keg on its side without issue, just let it sit for at least a couple of hours.
 * Not all kegs are created equal.  Most foreign beers (and some domestic craft beers) either will not fit in this kegerator or need a different keg coupler to connect to this kegerator.
 * I actually have this model built into my bar.  While it's not designed to be put into a bar, I made sure I have plenty of ventilation by putting 2-3 small fans near the back of the unit to keep everything as cool as possible.  I use small USB computer fans to do this plugged into a regular outlet.
 * This has drastically reduced my bar tab at some of my favorite establishments as I don't need to go out much anymore.

Hope this helps someone out there that has or is looking to buy this kegerator.
