So far, after 3weeks (and 18 bottles added) this unit keeps exact temperature. 
It is very heavy but seems well constructed. The steel racks and double-pane glass door can be removed once you uncrate it to make  it easier to move into place. The wood slats in front are unfinished (unfortunately). I feel that they should’ve had  a stain and/or sealer applied from the manufacturer. I will probably do that myself before it gets filled.
