I use in ocasional for some latin style songs, but it is very effective for use during peaceful public protests by NGOnor during summer and carnivals, sports hapennings,public celebrations etc.
Pros: interesting rear music effect, easy to use by non proffesional player, even by kids, students, very good for educational purposes, easy to find instructional videos..
Cons: should be cearful to avoid dissasemble. Be cearful with wooden block and small metal parts if used by kids...
