Product review (3 stars): Horrendous Service, Good Product
I've had the unit for about a year, gone through about 10 kegs and have only had to fill the CO2 tank once (initial fill-up).  It works great, though the drip try is impossible to empty without spilling if it fills up.  Luckily, I've had to deal with Haier only once.  The following is my adventure dealing with their Customer Service Department (each date represents a different day I called Haier):

5/24 - order shipped
6/1  - order delivered, did not receive parts including:
 1. 1 Beer Tap
 2. 1 CO2 Regulator
 3. 1 Washer for connecting CO2 Regulator to CO2 Cylinder
 4. 1 CO2 Cylinder
 5. 1 Keg Tap (American Sankey Type)
 6. 1 Cleaning Kit
 7. 1 CO2 Gas Line (Red Tube)

6/3  - called customer service, told them the parts I was missing
6/4  - faxed proof of purchase, was told parts would arrive in 7-10 days
6/6  - was told order was "processed" and would arrive in 3-5 days
6/9  - was told order was processed but had not been shipped.  it would ship "today"
6/13 - called, was told order not yet processed.  expect shipment 7-10 days after processing
6/15 - was told order would ship "today"
6/21 - got call saying parts would arrive "today or tomorrow"
6/22 - received package containing two 1/2" washers and a hose clamp (mind you the parts I was missing include a 10-lb CO2 tank and the package I received was so small it fit in the mail slot for my apartment)
6/25 - called and told them i received wrong parts, ordered new parts, was told to call back in 2 days
6/27 - was told that everything was good and to call back in 2 days to get tracking #
6/29 - called and was told that they needed my proof of purchase, faxed POP, called back and was told to call back next week to get tracking #.
7/6  - called and told that order would ship 7/9
7/10 - received package with missing parts

So after 12 calls over 37 days, I finally got the parts that should have shipped originally.  I had ordered it in hopes I'd have it up and running for my birthday, but no dice.  Hopefully, you'll never have to deal with Haier, but if you do try and be patient.  If patience isn't your thing, I recommend buying from another manufacturer.
