The sound quality is good, especially for this type of product and the price, the settings are intuitive and do not need to read the documentation. It works very well with our USB key and reads all of our mp3. Provide a mains supply, as most projection alarm clocks. Note that the projection of the time can be turned on / off easily. Most to us is that stopping the music needs to be properly awakened to find the button, which in the case of our teen is a plus. More delay for mechanically pressed the big stop button of his previous awakening! In short, an alarm clock that corresponds to our expectations.
