Bought this for my daughter's birthday. Without any prior experience playing a recorder, you may get some squeaks on the lower notes. That's common and easy to correct. Usually, you're blowing too hard or you're not covering the wholes tightly. Also, you can make a note sound sharp or flat by blowing too hard or by blowing weakly. It's a musical instrument. You have to LEARN how to play it. Go to YouTube for help.
