I thought additional space was about the only upgrade from my old, smaller refrigerator, but one week in, I can tell that its fresh air veil system definitely works and that the produces are staying fresher, longer. I bought 3 packs of strawberries as a tester a day before the fridge arrived - something I never did as the strawberries would start to get dry after just 3-4 days, and the third/last pack to date is as fresh as the day one! I love this refrigerator! 10 out of 5 stars!
