Product review (1 stars): What a piece of junk
Researched this type of equipment extensively before purchasing. Choices came down to GE and Marvel. I selected Marvel because of their reputation in medical refrigeration. I purchased two of these units as part of a remodel project. One unit failed immediately following installation. The factory blamed the electrical circuitry specifying each unit must have a dedicated ground. The electrician provided the additional wiring but lamented that in his twenty plus years in the business he had never seen this type of requirement.
After sorting the electrical issues the units functioned fine and smooth sailing lay ahead, or so I thought. Subsequent problems with both units finally led to them both being replaced by the manufacturer. Now two years after the initial units were replaced, one unit no longer functions and I just discovered that the second unit is currently sitting with an internal temperature of 50 degrees F. Big party here this weekend and no working refrigerated drawers.

I'm giving the product one star only because it hasn't crumbled to pieces, yet. Stay away, you've been warned.
