I don't have the 320, but the 325. I also have the 4 door fridge. We've only had it for a month now, but we're living in it. We have not had any big problems. My main complaint is the black, high gloss, Estone counters. They scratch VERY easily. I love the fridge and don't have an issue with keeping it cold. Although, I have to say, we live in the Upper Peninsula of Michigan, so although we feel like it's sweltering hot, it's really only in the high 80's low 90's. We did notice that the air conditioner has a hard time keeping up with the temps. We only have 1 air conditioner and I've seen some posts here that talk about a 2nd unit. We'll be checking to see if adding this would be a possibility for us.
