I put this in and sealed it and put it a bit above, I think, medium. Next morning, with an empty box I had 26 degrees. It now sits on 38. I now have a 1/2 barrel, a corny keg, and some misc bottles in the fridge and box and it works great. I have 3 fans going as explained earlier. The inside of the fridge is molded plasvt like a chest freezer. Bottom line: I love it as it is quiet and does a great job.
