Not acceptable for this price

Perfectly clear that there is no peak instrument at this price.
However, this device is a typical example that you buy ultimately too expensive if you buy too cheap.
The mere processing is so underground that is not to be understood as a prestigious music store such a thing can ever take in its range. The speakers at the bottom are unprotected, the paper cone is free. At the first audition the sound on the left side was weaker and accompanied by a sharp creaking. The solution: sawdust between housing and beading.

The sockets on the rear are unmarked and squint through holes that were probably created with the shotgun.

The keyboard is fine, the integrated stand and cover are practical. However, there is a risk that you will damage the display when you forget to fold up the music rest before closing the lid.

The "sound" is unacceptable, even if one sets lowest standards. Each and every Daddelautomat sounding greeting card listen to better. The sounds of the keyboard are unbearable, the rhythm sounds like Orff group in kindergarten (sibilant hissing-click-clack). All suffering is reminiscent of the painstaking efforts of a laptop sound card to accompany a computer game.

There are worlds between this unit and a brand of Keyboard 200-Euro-class.

Ultimately, you have from this part simply nothing.
