Have this equipment due to good reviews bought (by another provider) after unpacking at Christmas we have packed the unit immediately and will be sent back. It was almost impossible to insert the batteries as the thread for the screw of the battery door was broken. Before and rewind went at all. The additional keys are a joke, not to recognize as applause or rocket launch. After the first impression was more than bad could the scratchy, poor sound quality it also not change anything. We were looking forward about it that's ever come a sound from the device. However, if you will not be entitled to the sound and caught a functioning unit and simply wants to play only one cartridge you can probably live with that. The little I think it is not matter anyway. Think drann - batteries or an AC adapter must be purchased separately!
