So these things are pretty handy -- they do a good job at cleaning/dusting hard to reach areas that we don't normally get to with the vacuum, like baseboards and corners of walls. But, the product received a D score from Environmental Working Group because it contains Mineral Oil (a petroleum product). They are also by nature a cheap disposable thing. We would prefer to purchase reusable, long-wearing items that are made from eco-friendly materials. So, good for what it is, but I would not purchase.
