Criticisms:
1. There is no charger / power supply here. This you have to purchase an extra.
2. There are no batteries there. In addition, the device requires R14 6 chunky, medium-sized batteries, for whatever reason.
3. The CD player does not play MP3 CDs.
4. For technical reasons, the CD player jumps when moving the unit for which it was originally designed.
5. The speaker is attached to the rear side. If the device is, you can hear little.
6. The sound is poor.
7. The microphones are of poor sound quality and must be turned on and off, so they do not feed back. Normally one would obstruct a simple feedback filters, so that the device does not start according to whistle when the microphones are placed back to the unit. Children do not understand why the thing to whistle now suddenly begins.
8. A real karaoke function There is no course.
Overall, I can not recommend this device. Too bad that the original good idea is implemented so inconsistent.
