This little gizmo is really nice. Super easy to set up. Just had to pull off some plastic, open the filter,  and plug it in. Directions from there were very easy to navigate and made very obvious with the directions and stickers on the machine. Started up and it puts out a lot of air when you want it to, or kick it to auto and just let it do its thing. Having a family and approaching flu season, this is an awesome addition.
