I got the amplifier quickly. The email Store service is great! On my questions a helpful reply was sent quickly. I would shop there again. The amplifier itself is robust. For the price it is always sufficient. He is not the loudest in conjunction with low boxes (I know not how it is with more expensive). To all who want to build mobile jukebox eg NE, are well advised with the cheap amplifier! Much more than that, what you may not expect at such a reasonable price!
