Product review (1 stars): Frigi-don't !
If I could, I'd give it zero stars as far as temperature control goes. It will go down to 33 degrees F, but if there are any cans stored in the back of the unit they will freeze and burst, But hey, who doesn't like to clean up a mess ! With that said, it will NOT hold 138 cans. It will hold maybe ~ 107. I had to put some foam insulation in the back of each shelf to keep cans away from the cooling panels so they didn't freeze.

I have it set at 41 degrees, the readout says 45 degrees. I put a thermometer on each shelf and get a +/- 10 degree temperature reading at each location.

Such a shame as all they needed to do was put a $10 fan in it to move the air and cool the entire interior to the same temperature.
