Query: Horrible User Interface

This is the most horrid clock radio ever. The user interface is terrible, and the physical unit is huge. The time receiver antenna is a monster and highly ugly. I couldn't figure out how to set the alarm or change the radio station. This truly has the most horrid manual and the buttons were clearly not designed with the user in mind.This item got sent back and a $15 Emerson clock radio is vastly superior. The company clearly does not elicit feedback from real humans during the design process. I can't imagine anyone actually using this device outside of their engineering labs.
