As the other comment states, the batteries come out of their place with the slightest touch, so you have to put something to keep them in place. Cheap construction compared to a well-known brand, but the price doesn't differ much. The screw doesn't lock anymore after one use, so it immediately needed something to keep it closed after installing the batteries. The only good thing is that it has relatively good sound and enough options for the microphone. However, if I had bought it as a gift, I would be ashamed to give it, what a shame.

It had 2 problems:
1) The screw on the batteries did not turn as the quality of the plastic was not good and it stripped, losing the turns with the first opening.
2) The batteries come out of their position with the slightest shake and stop working. A big problem if you think about how kids play with them.
