Looking for an MP3 player in my "den", I saw this. An MP3 player alone can easily cost €100, but this BP 108 A is "all in one" MP3, amplifier, speaker and mixing desk, plus, it's also battery or mains, a great package for €70.
At full volume, its not gonna shake your house, but at sensible listening volume it's quite a pleasant sounding machine and not too big as to block a small room and light as a feather.
Mine is on a 35m wall bracket so I can spin round to make adjustments to the sound or change the SD card.
I tried the mic & guitar together, found some pleasant sound settings for a solo performance, but won't be using it for that, as 15w rms is not enough "punch" for my few live venues.
After a few re'charges, the battery gets its feet and lasts much longer than the first charge. Mine stays on most days as back ground music in my house.
No strange noises or problems yet, in fact I cannot find a fault or problem with this little beauty.
For this price, it's a beauty.
