The fridge portion of this unit works fine. It swings between 33-37 degrees, and since 35 is nominal, I figure that's not unreasonable, especially for an EnergyStar appliance. The shelves are a little flimsy, but it does the trick, and is garage-ready (for most environments), so it fits the bill in that regard quite nicely.
The freezer portion, on the other hand, is awful... It swings from -6 to 30 degrees. When I first used a freezer thermometer to measure this, and it showed me this swing, I didn't believe it. A buddy had a USB data logging thermometer that he used for his RV, which you stick in the freezer or fridge, and wait a couple days, and then download the data, so I gave it a whirl. After a couple days, I had enough data that I could graph it, and I confirmed that yes, it does sweep wildly like that, over a period of about 2.5 to 3 hours. It takes about 2 hours for it to warm up from the coldest temperature (-5 to -7 degrees) up to the hottest (28-31), then it goes into a rapid cooling cycle which cools it temperature down to the coldest temperature again in about a half hour. It does this constantly, throughout the day and night.
We already returned one (under Geek Squad), and while they shipped out a new one and took back our old one, Geek Squad somehow canceled my GS coverage without refunding me, so I had to hassle with that (1.5 hours in BestBuy customer service, and then emails back and forth, finally resolved). I will likely be returning this one, and having them replace it with a brand that actually works (if they will)...
