    Sensational Find
  

*by H***Y on Reviewed in the United States on October 3, 2019*

Good quality has been hard to come by as I feel I can’t trust the reviews I read as I know some have been bribed. I can honestly say I was shocked to find this little gem especially for the price.  I have used it daily since it arrived at my doorstep. I’ve been taking it back and forth from home to work, but I will Instead buy a second one, and most likely a couple more as gifts, as Christmas is around the corner.

    So Cute & Simple!
  

*by A***A on Reviewed in the United States on November 18, 2019*

I bought this for my desk at work and everyone who walked by wanted to know what it was. It really pumps out the vapor and it is almost completely silent. I would say that if you use this for a 9-10 hour work day, you only have to fill it in the morning once and it will last the whole day. If you need it running longer before a refill is needed, there is also an intermittent vapor mode. It is barely 6" tall with about a 3.5" circumference at the base so it is very portable and does not take up much space. The LED mode isn't very noticeable in a bright office, but that's okay. It would make a really cute child's humidifier & night light combo if placed by their nightstand. It's very handy to have a USB-powered model as well because I can plug it right into my computer, monitor, or docking station. If you need to plug it into a wall, you will need to have a wall outlet to USB converter as it does not come with one. I'm actually ordering two more right now so that a co-worker can give them to his wife and daughter as Christmas presents!

     Holding the button for 3 seconds turns on/off the light and pushing once turns on/off the humidifier. Super cute design, nice size. Portable,  as long as u have something to plug the USB into.
