Jean Paul USACL-300 Student Clarinet

When Clarinet arrived I was delighted with it, just what i wanted, good tone. I have been playing it everydaysince. A couple of days ago 22 Sept started having problem getting below e flat ( lower register ) after a bit of investigation found out the spring 3L on fingering chart was loose and the key which should normally be closed was remaning open. The spring has since falling out. The clarinet arrived 14 Aug malfunctioned about 22nd Sept just over two months old, so raises a question over the build quality. I do have warranty but don't expect to have issues and have to send it off after only 2 months .

is good
