Query: Broke within 6 months

We purchased this product from Costco luckily because it broke within 6 months! The cold water was room temperature. It's great that it's energy efficient, but when you're working on something and have to wait a minute for the hot water to get hot, you forget about it as you go do something else while you're waiting. We're a three person office, and none of us wanted to get another vitapur cooler.
