Query: Junk

I bought the Cup-At-A-Time as a water-heater for my dorm room, and for a while it did it's job merrily, but several months after I bought it, it began to sputter out on me. Once, while loading the water after brewing a cup of tea fifteen minutes prior, steam shot out of the fixture and a piece flew out. It appeared to be a regulating apparatus that stops and starts the intake of water. I managed to put it back in, but time and time again, it dislodges. Another problem I noticed is the lid does not sit securely on the machine, and can be easily opened by a small child that may not know any better. I plan on returning this fixture to the store I bought it from for something different.
