Review on Compact Green Portable Travel Humidifier with Auto Shut-Off - Ideal for Car, Home, Office, Hotel! by Joe Daniels

I couldn't find a suitable water bottle. If you're okay with having to refill it a few times a day, a mini sprayer will do for me, but I bought this to keep my plants moist while I was away for a few days. It turns itself off after a few hours and takes a few turns before it turns back on, even if there was still water in it.
