Rapid delivery. Easy Install. Immediate Results. Recommend Air Filter with purchase. My son was always a bottled water drinker. Up to 10-12 bottles a day (add that cost up). With this Refrigerator and Water Feature (and a 20oz tumbler Xmas gift..LOL) My son ONLY drinks his water from the fridge feature. This product is cost efficient in the long run for us. We haven't bought another bottle of water since. Love it!
