Review on 🌬️ Enhanced Portable Ultrasonic Humidifier: A Compact Solution for Optimal Air Moisture Control by Timothy Weems

That little piece of junk sounded great. The idea of using an ordinary water bottle as a reservoir for a tiny humidifier for a long time is simply brilliant. Unfortunately, it only works for 5 or 10 minutes as the performance gradually drops to zero. The problem I found was that the bubbles start to stick to the edge of the transducer and eventually build up to the point where they absorb the ultrasonic waves. No ultrasonic waves = no fog. You can use the included cotton swab to remove the bubbles, but it only works for another 5 minutes before you have to do it again. Do yourself a favor and buy something else.
