Query: Although speaker sound is good.

For a small speaker I do agree the sound is good. However, it did not (Perhaps I read the description wrong) come "with" a dc plug. You can buy a converter so that may not be a biggie for most folks. There were "no" instructions included at all. Of course it's a simple little product and I can't say there is a big reason to include much detail. If you are looking for something to take on a camping trip or mayby even to play your Ipod in the garage it's not a bad system. But, if you are looking for a really good charger with a nice playback feature and even a few bells and whistles this is not for you. Overall, I can't give it a great review but for the money I can't complain much about it either.
