The quality of this ultrasonic piezo speaker appears to be good. I replaced the dead speaker in a cool mist humidifier with one of the ones from this order, and after ~15 minutes of nothing, the humidifier started working as good as new, and has continued to work normally ever since.As of 20241208, it's barely been 24 hours since I installed this part, and so there's nothing to say about long-term durability. I'll update this review as I know more.

I could get them to move but not generate mist in my humidifier.

We have two "safety first" humidifiers, both of which stopped working correctly. These indeed fit and they work, saved both humidifiers from the trash can.One of my humidifiers had red and black wires, one had the yellow and blue, even though they are 100% identical on the outside. It's easy to figure out though.Red wire goes to yellow wire, black goes with blue. And even if you aren't sure, look at the positions of where the wires are soldered on the disc. Easy fix (~20 min), the only question is how well they hold up in the long term.

Humidifier stopped working. After replacing the disc, it is working like new.

Bought these to repair an ultrasonic cold air humidifier. I broke the ceramic transducer on it when cleaning. I was pleased that these fit perfectly. The only problem was that the wires weren't long enough, so I had to cut some wire off the broken disk and do some splicing.

Attached 2 pictures. One picture shows the transducer before installation (on the left) and after used in a humidifier for 2 days. The second picture shows the transducer installed in the humidifier. The transducer works fine at first, but has deteriorated to a point that it was not usable (no mist produced). The upper coating layer, responsible for the ultrasound vibration that produces mist, broke and fell off. Tried two devices in the package of 5 with the same result. Go figure.
