This is a really great duster that works well for places under the couch.  I have a sectional couch that just collects EVERYTHING!  It's ridiculous!  I used this under my couches after vacuuming and it works really well.  I have to clean under the couch at least once a day thanks to pets and children.  Swiffer 180 Dusters TRAP + LOCK dust & allergens for sure!  It picked up the nasty pet hair under the couch that my vacuum cleaner doesn't get.  I feel it works better than my static duster.  Fantastic product!
