Do not buy this - get an electric one. This is simply a cup and a plastic funnel that you put hot water in.

This was not what I was expecting. You pour hot water, not boiling, in the base and add the disc to inhale the fumes. I used mine with essential oils and I get better results over a sink full of water. Does not produce steam like I would like. Easy to use, made for all parts to come apart. Easy to clean.

After reading the reviews here I wondered why on earth I had purchased this contraption. But I decided to give it a try because I had a VERY stuffy nose, it was late at night, and I was desperate. When I breathed in the vapors as indicated by the illustration on the directions not much happened. Then I tried placing my face/mouth directly on the unit creating a "seal" and breathing in deeply. The medicated vapors flooded my throat and lungs and then to my surprise I was instantly able to breathe freely through my nose! After six days of dealing with an incredibly stuffy nose, this seemed like a miracle to me! The relief was temporary but could be attained again by repeating the process. It really did help to open my nose, cool my throat, and quiet my cough. This will be coming along with me on vacation next week!

It is almost useless. If you would trust your youngest child with
hot chocolate invest in a good one with a power cord, or at least batteries.
But it might be useful if you have a child under 5 that would burn themselves with a real steamer.

I was very, very disappointed with this product. It's completely useless!! It's equivalent to putting warm water in a plastic cup. What a rip off!!
