Review on JISULIFE Small Humidifier - USB Rechargeable Ultrasonic 3600mAh Battery Operated Top Fill Humidifier with Dual Mists - 5-12 Work Time - Bedroom, Auto Shut Off - Portable Desk Humidifier for Home Baby by Steven Ripley

Don't buy this! This is by far the worst thing I've ever bought online. I once bought a "tabletop Christmas tree" that looked like a piece of metal with several shredded pieces of water weed attached to it. It's even worse. I followed the instructions, re-read the instructions, read the suggestions in the FAQ here. I used the second set of filters and tried everything again. All this piece of junk did was let out a high-pitched squeal and release a few puffs of steam for the first few moments. I've turned it on and off, I've let it run briefly, I've let it run for hours. Nothing. Just a scream. I just wanted a humidifier that wouldn't knock out my bedside table. It's not like this. I don't know if it's defective but judging by other reviews it seems like this product is defective half the time.
