Mini Portable Bottle Cap Air Humidifier with USB Cable for Office Home, Pink Color

Doesn't attach, just sits on bottle. Once water gets low in the bottle, it is prone to toppling over. Also, periodically makes a loud (or it is at lease loud when you're sleeping) whistling/squeeking noise.

This was such a great innovative idea! It is perfect for my desk space at work as it is such a dry environment in there. Works wonderfully, you can really see the water vapor in the air just like in the picture! And I see a great amount of water decrease in my bottle through out the day. Definitely worth buying if you are considering one.

This product is poorly manufactured!!!! It does not twist onto the water bottle. I tried several different water bottles and to no avail, it still does not fit onto the water bottle. The product description and instructions are poorly written in broken English. The humidifier will turn off by itself within an hour of operation. There is little to no vaporization that occurs from operating this horrible product. I will never purchase from this company again in my life. Total waste of money and time!

i ordered Jan 1st and it just got her today Jan 27. I had forgotten I ordered it! I was excited and opened it up to use and it doesn't hardly put any moisture out. This product is crap! Don't buy!!! As u can see in the pic it doesn't put hardly anything out!!! Very disappointed! Not to mention it just sets on the bottle not actually screws on to the bottle.

Worked well for a while then stopped. Replaced the filter and same thing again. Not a bad little device for the money.

Came with just topper and 2 filters. Seems to do the job. Need to rinse out every few days otherwise it gets to smelling bad

it is ok not want i acppet

Starts to steam immediately once plugged in. Does not get hot to touch. However does not fit all basic water bottles.
