There seems to be 3 types: the Ploeger one that attaches to the bell of the sax which works well as a reflector but every now and then falls off and breaks; the ones that fit onto a mic; and one on a flexible arm that attaches to a music stand. I was looking to try the third one of these as I've just broken yet another Ploeger. On the occasions I play through a mic, I can usually hear myself through the monitors anyway. I only use the reflector on tenor, don't need to on alto or soprano. Cheers, Pete
