This product has some great features.  I love the fact you can throw away the dusty mop after a cleaning session.  It picks up dust very well from most  surfaces.  However, I don't think 1 duster goes very far.  I was able to dust the staircase banisters, the bedroom headboards and 4 windows before the duster lost its effectiveness.  Keep in mind, I am a cleaning fanatic and dust my house weekly, so there is not much build up to begin with.  Overall, nice product for its ability to pick up dust.  Minus one star for its short lived life span.
