These are the times that are trying my soul; kids haven't had these things 24 hours and the problems are popping up...
One of the speaker wires on my 10 year old's Aeon snapped somehow. It was working fine this morning, and about a half hour ago it stopped making sound. Took the pommel off to find this:

He hasn't been dueling that hard, and I'm the only one who's been handling the chassis to remove and replace the batteries, and I know I've been as careful as can be.
I've already emailed Ultrasabers about this one - this is definitely getting sent for a repair job. Ugh.
