Cheap, but with restrictions

But: No automatic shutdown, the batteries are sucked empty if one evening to check whether is switched off forgets.
Evil, annoying feedbacks if the microphone volume is too high psyched.
The microphones are only toys (little kids love it, but objectively speaking they are completely useless)
Stiff CD door (only for my device?)

But for the price it stays at 4 stars ...

ADDITIONAL for 2 years:
Maybe not uninteresting: Even after 2 years of intensive children use the device shows no weaknesses, nothing is broken, frayed nothing. The CD player works as the first day (which no longer applies to some CD's in the children's use). The extra selling rechargeable batteries, have now safely enter also played several times, I probably would have now produced a small closet full of waste. The child, now two years older, the unit value as before. Since I myself have now invested in a fairly high-quality hi-fi system, I am with the sound of the instrument, of course, no longer satisfied. But the 4 star keeps it on, if only for the longevity with which I - did not expect - honestly.

ADDITIONAL after 3 years:
After about 2 1/2 years the stiff flap has (so) taken its toll: The hinge on the side where the door is mechanically braked, has adopted a short clicks, it's broken.
Interestingly, this has little effect on the operation. Now you have the flap while optimally push with both hands, but they snapped cleanly, and when it is closed, then you realize not even know that something is broken. So actually still works all easily ...
