Works but shipping was slow

The product itself is functional and creates mist efficiently. However, delivery took longer than expected.

Perfect for DIY Humidifier

Used this to build a custom humidifier for my greenhouse. Works flawlessly with a 24V power supply.

Efficient and quiet

I was worried about noise, but the oscillator is very quiet. Mist output is consistent.

Good module, minor wiring confusion

The board works well but the diagram on the back was a bit faint. Once connected, it produces a nice mist.
