Suggestions Needed - iontophoresis-device

Hi Guys,

I purchased an iontophoresis-device a few years back, unfortunately it wasn't very effective for my palmar hyperhidrosis (which is pretty severe). I've started botox treatments now, but I was wondering how I would dispose of the device? What have you all done with your devices that you no longer use? I'm located in Vancouver, BC and haven't been able to find anyone that needs it, so any suggestions are welcome.

Thank you.
