Let me be honest and say that I don't need 45 slots to chill wine. I really don't even need a dozen slots but why not get the best you can have? I usually chill about four bottles at a time. Occasionally I will add more. This machine has a temperature level you can adjust and it seems to keep wine somewhere between 45-60 degrees, although I usually prefer mine ice cold. The chiller has a digital display that reads the temperature the cooler is set on, but it doesn't tell you when the wine has actually reached that setting so I opt to put wine in about 10-12 hours ahead of time. It's a great chiller and works well for us, however, I don't need it to be so big and bulky. I also wish I could adjust the temperature down a bit colder for my preference. Another gripe with the temperature is that since it isn't sectioned off, I can't place any in a top section for cooler temps and a lower for warmer temps. Additionally, when you stock this machine, you have to keep in mind that you're stocking back to front so lesser used bottles should go in the back. This keeps all bottles relatively the same temperature so if I am chilling a Riesling, a Merlot, a Moscato, a Blush and a Zinfandel all at once, I can't control the temperature for these different types of wine. Now, I know I sound like I am complaining but overall this is a great item. It needs a little more work to be perfected. I also wish it came in a 10 bottle capacity because 45 bottles is just too many for me. I don't think I've ever had more than 12-14 bottles at a time, and even then, it was only because I knew I had room for it and knew we might be snowed in for a little while.
