Product review (4 stars): Good unit, but some cheap parts and poor packaging
Recently purchased and assembled this unit as a gift for my father. This is my honest take on the unit from my experience.

First things first, the packaging that it was shipped in was somewhat shoddy. Double-boxed, but the bottom of the interior box was ripped out completly allowing it to move inside the outer box. I believe this led to at least one of the following defects. After unboxing, I found that there was a ~4" gash in the side of the unit; the paint wasn't scratched but it is very noticeable. Part of the metal frame at the bottom of the door face was warped outward, which until smashed back flush with a hammer was interrupting the door seal (which would have allowed cold air to escape). Finally, one of the two interior shelves was hastily shoved into the interior of the unit during packaging and was half bent; I could not fully unbend the shelf to look "normal". If we didn't need this assembled and operational the next day for a surprise party, then it would have been sent back for a replacement unit.

Beyond this, the unit itself is pretty well built. The parts are all of average quality, and the unit itself holds sub-40 degree temperature well. The CO2 and beer line tubing are both PVC based, I will be upgrading the beer lines to an antibacterial sanitary grade tubing at a later time (Ultra Barrier Silver). The CO2 tank regulator is only a single gauge unlike most others on the market that show both the tank pressure along with the line pressure; this isn't a big deal but it would be nicer if it was dual gauge in order to monitor the tank pressure to know when you need to get it refilled. The tower comes with interior insulation, which I have found to be very good as it keeps it cold enough and to not pour a ton of foam when you haven't poured in a while, and a lot of other towers on the market do not come with interior insulation. The taps are decent, but drip for a minute or two after pouring anything; I'll be upgrading these to Perlick taps for sanitary reasons regardless but they suffice. BE SURE TO CLEAN THE INSIDE OF THE TAPS BEFORE USE, there was some black "gunk" (almost like a grease) that was just inside both of our faucets. The keg couplers were fine. There were no issues with the CO2 tank itself. All of the supplied hardware (line T, hose clamps, etc) were sufficient.

My final gripes about the unit. The sides (but not front or rear) get HOT on the outside, more so than any minifridge I've ever owned (which is essentially what this is - a glorified minifridge with taps). The drip plate is also just a piece of cheap rectangular plastic that sits on the top of the unit under the taps, and unlike most drip trays on the market it does not have an inset curved shape to set flush around the tower, it just awkwardly sets there and looks out of place on a $500 unit.

The instructions were easy and simple to follow, if you're mechanically inclined in the slightest, then you won't have any issues assembling this. All in all this unit was worth the money over restoring an old Kegerator that we had with a new dual-tap Kegko kit (that project was about $80 less altogether than buying this new unit). I will however be upgrading a lot of the components here - drip tray, taps, beer line tubing, and possibly the regulator.

UPDATE 03 JAN 2018:
Just wanted to add a couple of notes after a couple months of use and upgrades. The included PVC lines have been fine as long as they are cleaned (we use Regal Marketing Kegerator Beer Line Cleaning Kit), we haven't switched them out to a different tubing yet but haven't had any issues after a couple of different kegs. The included spring-loaded taps tended toward being leaky here or there, mostly probably from not being completely pushed back into the closed position by tipsy guests, but even then some slow drips still continued from time to time. The short tap handles don't help with that. We've replaced the taps with Perlick 630SS taps and haven't looked back - they're wonderful. I recommend getting a thermometer to keep inside the unit, once we got the temperature dialed in and stable for a few weeks, we were able to dial back the temperature setting knob which helped with the sides of the unit getting so hot. They still get a little warm, but not as much as they did at the start. We also added a distributor T with individual line valves to replace the included CO2 line T/Wye, it's just an extra preventative measure to keep CO2 from leaking from an untapped line when we only have 1 keg installed. Overall, we've been pretty satisfied with the unit after some upgrades.
