"first time using a bow buddie with a 6 year old student. up til now she did not like to use the bow and we've been studying pizz, she couldn't seem to hold, until i put the bow buddie on and she loved the pink color and it gave her an instant proper hold. so this is a great teaching tool, it's comfortable. only down side is you have to unscrew nut to get it on and off, and it doesnt fit into 1/4 size violin case attached to bow very well. i dont know if mom will screw on and off for her at home."
