you really have to see the duster in action to believe it. The duster is absolutely safe - it picks up dust like a magnet picks up iron particles, and it is not at all abrasive and does not creates swirls and scratches. Only thing you have to remember is - do not wipe a wet car using Jopasu. The secret behind Jopasu is that, each strand of the duster is wax coated. The wax coating will get damaged if you wash it, so you should never wash it and should not use it to dust a wet car. It takes me hardly 5 minutes to clean my car. See this video - this is how Jopsu also cleans.
