Quality:
It appears that the battery compartment is inferiorly made. Battery is unable to make connection, making sound go off and on during playing.

Sound:
It sounds great, when it works. The first one I bought stopped working a few days after I brought it home. We changed the battery. That lasted for a few days. Changed the battery again. After 2 months, it stopped playing all together. We brought it back and exchanged it. Less then a week with the new bass, it happened again. When I inspected the battery it was clear that one side of the battery was not connected. Try as I did, the battery would not connect properly. And there is about 1 inch of wire to work with, making it nearly impossible to get fingers into the battery pack to secure it. Wondering if anyone else has had this problem?

Overall:
Bought this for my daughter. It is not reliable. What use is a bass that makes no sound?
