Way better than I expected!
**USE AN APPROPRIATE USB POWER ADAPTER! TOO LOW AMPRE POWER ADAPTER WILL CAUSE OVERHEATING AND MELTING OF THE CORD** THIS IS NOT SPECIFIC TO THIS PRODUCT! First, get a good USB power plug - not a cheap low-power one. This device works on ultrasonic motion, which requires a bit more power than a cheap USB plug will give. Going with cheap, you will get a hot cord and possible melting! I used an Anker power adapter and no heating up, no melting. Using a cheap plug caused the cord to get hot and eventually the unit shut off - most likely the cheap USB plug did. I have a few diffusers. The common thing with all of them is they kind of go all out, then turn off after a few hours due to the water level. Not this one! Instead of a strong intense stream of vaporized and diffuse water, it gives a less forceful, more even, and consistent dispersion I was extremely skeptical at the advertised "fire" effect, but danged if it wasn't accurate! This is beautiful! I filled it yesterday, put a few drops of eucalyptus and lemon, and it's run for at least 10 hours. The room was fragrant, but not so strong I'd get a headache. The only negative, is there is only one speed or setting. It's either one or off. To accommodate this, adjust the essential oils to be stronger or weaker. The light effect is truly amazing. I can't help but keep it on the default orange, but cycling through the colors is neat. Also, once the color cycle gets to a color you want, just tapping the light button sets the color. It's doesn't keep it though, when you power off. But I'd recommend this to anyone who wants a longer-lasting diffuser! They should include a power supply for this unit though. Being that is has specific power requirements, recommended power supplies should be listed, at minimum. Read more
