It's Gentle
I've been using a manual nasal syringe/sprayer for YEARS.  I like this because I am able to get all of the solution in (nothing left over in the bottom), and the stream is gentler than u am able to do with the manual.  I am concerned and want people to know that DISTILLED WATER is what everyone should use, and remember to let it dry out (leave it open sometimes - don't keep it wet and closed up).  I like that it can be carried in a compact manner.  I can't comment on the battery life at this time.
