Query: A clock that does not keep time!

Generally, I don't take time to review products. In this case, I had to and my wife even insisted I do the review. This clock cannot keep the time and maintain it. After many trial and errors, putting brand new Duracell batteries, setting time and after every time the clock would start running fast. Basically, this is a clock that does not do its primary function correctly. Finally, after few years and pain, deciding to junk it.
