Product review (5 stars): Great Refrig /Freezer with bottom drawer freezer.
Purchased a unit like this locally about a year ago and have had no issues with it.  Our unit is white not stainless to match out other appliances. Our freezer is set 4 and the refrig is at 2.  I always use an actual refrig/freezer thermometer to get the settings accurate.  The unit is not noisy, does not run excessively, the ice maker works fine, the refrig and freezer areas are well planed and lighted, the refrig door has great storage.  I've read  where some people had issues with a drain in which a bushing was too tight and may have restricted drain flow?  Never had any issues with this.  Apparently this issue was in older units and was solved by replacing a bushing made with softer material.  I personally feel that making sure your temps are in the correct range for both the freezer and refrig are very important and need to be verified with actual readings gained by using a refrig/freezer thermometer (get from your local hardware store) as also noted above.  Love the refrig portion being on the top as this is the area used about 90% of the time.  Note made in America.

Update 8-31-2016.  Unit is still running fine.  Have had no problems or service calls.  I spoke to a neighbor who had a similar unit and had some ice buildups due to the drain tube freezing up...don't know if he installed the revised tube design with larger / softer bushing or not.  Recently he resolved the line freezing and ice build-ups by adding some aluminum foil around the drain tube to transfer heat from the compressor area as he explained. The foil acts a a small heat source, so I suppose a small heat tape would do the same thing.  He also said that Viking has a kit that can be purchased to also solve this line freezing and ice buildup problem for a cost of about $200...
