6PCS 20mm Ultrasonic Mist Maker Fogger Water Fountain Ceramic Humidifier Discs with Wire

Based on YT video by Dustin Rogers, gave these a shot when this unit stopped producing mist. Took about 15 minutes totake the base off the unit. These 20mm discs give you the outer clear plastic ring (which other Amazon seller's parts do not. I decided not to solder to the board, just clipped the two lead wires from the old piezo disc, shipped a little more lead wire and used small wire nuts so this can easily be repeated when/if the replacement piezo gives way. On this unit, the red wire on the old disc was soldered in the center, so I just connected the two red wires, and had the yellow mating to the black. Really easy and works just like the original equipment did.
