Pros:
Works really well. I play violin and wind instrument in a band and need to swap with minimum fuss. This holds the violin and bow very securely when on stage. I use a clip on instrument mic and love the fact that you can clip the mic lead to the stand and place the violin into the holder and pick it back up without any fuss at all. So far it seems like an almost perfect stage arrangement when swapping between instrument.
Cons:
Nothing
