The only downside is weighty but unfortunately the sound quality. The sound is muffled and topfig and corresponds to that of no-name radio alarm clocks 10-20 class. Of course you can not expect miracles in such a small device. However, I know several radios with similar dimensions that provide a much more pleasant sound to his feet.
Conclusion: If you want to be woken up only briefly and whistles to the sound, which can be happy with this device. Who wants to listen for an extended period radio, is rather wrong.
