Recently I purchased a Tango [/ and the band was broken. I used acetone (nail polisher remover) to dissolve what I guess was super glue. The acetone evaporates so I had to pour in the acetone into the [/ twice but then I was able to easy pry up the insert. Also, when I first tried to pry the insert I bent on of the tynes (for lack of a better word). I didn't move it much but I had to push the tyne back down to get the [/ to work properly.

There was another post that pointed me to this website:

Yes acetone dissolves cyano aka superglue
