Customer service sucks

Asked to cancel order 3 times. They still sent it.


My family bought 3 bought three smart humidifiers. We received the standard model. We contacted customer service who recognized that we were given the wrong product but they never got back to us despite saying they would. We have reported them to the better business bureau. Beware.

Humidifiers have come a long way!

I’d never thought I’d be excited about a humidifier, especially one with Bluetooth technology that I can control from my phone! Very easy to set up and go!!
