The 400 Series Tri-Temp Bottom Load Water Cooler is such a great addition to my office. I work from home for a bank, so I'm constantly on the phone and was having difficulty consuming enough water on a daily basis. This water cooler has solved that problem! I set it up right next to my desk and I can refill my water cup any time I need to! The cold water is nice and refreshing and I love the hot water function. I put some hot cocoa packets in my office and I can now have a treat any tiny. And the child safety link on the hot water dispenser is such a great feature. I also enjoy that it's a bottom loader. There's no way I would be able to install a top loader by myself. This water dispenser checked every box for me and I couldn't be happier with it.
