I have two sabers where the adhesive on the sound board has begun to weaken, and separates itself from the battery pack when changing batteries. A little scary, but no harm done. I just stuck them both back on.
However, I am concerned about the next time we duel with the boards hanging on by a thread like this. They could come loose, bang against the sides of the hilt, and break, or short out.
Any suggestions on securing the board better than it is now?
I would probably suggest getting a higher quality double sided tape or adhesive pad of some sort.
