I got the 400 Series Tri-Temp Bottom Load Water Cooler to make it easier to get my recommended ounces of water per day. I can really only tolerate drinking cold water so this gets rid of the warm water excuse. I also love the hot water feature so I can make hot tea whenever when I'm cold. The best part about this cooler is that I don't have to try to flip a 5 gallon bottle of water over my shoulder to load it.
