I have a tabletop Spider nebulizer I bought some 15 years ago. When the virus situation began in February, I have used it to nebulize silver at the end of each day to defeat anything that may have been transmitted to the mouth and/or nasal passageways. I bought the Omron on the advice of asthmatic friends who said they used it and really liked it. Now I know why they said that. It is easier to use and clean than my tabletop, more quiet, and delivers more material than my other machine. Because it can operate on batteries, I don't have to plug it in and be tethered to the bathroom. Wonderful, thank you.
This is a very well made and efficient AC adapter. Saves on batteries. Only complaint is that you have to remove the 2 AA batteries to plug the AC adapter in. Then again, we haven't found owned a nebulizer yet that had an internal rechargeable battery that didn't need to be removed to be recharged.
I am very pleased with this product.
