Excellent for pet treatments.
I use this to give medical treatment for my pet's respiratory ailment.  She really appreciates the quietness as opposed to the plug-in bubbler style of nebulizer.  You can just put this in the portable oxygen tent with the animal, and zip it closed because you don't have to worry about a power cord.  It works great, and gives off a very fine mist.  I may use it myself in the winter when the air is dry.  The company sent me a followup email to make sure it was working satisfactorily, as these are pretty delicate.
