Amazon calculates a product's star ratings based on a machine learned model instead of a raw data average. The model takes into account factors including the age of a rating, whether the ratings are from verified purchasers and factors that establish reviewer trustworthiness.
The duster sticks to magnetic white boards which is good. Works okay. You need to put some amount of pressure on this duster to erase properly. Kids don't find it that easy to quickly erase their work.
Product received is non-magnetic and quality is very bad, didn't match with the picture shown. Not even that I've to pay for the returning the product to the supplier. Never recommend to anyone for purchasing this product.
Transportation charges too much. Nearly same as that of the product. The magnet is just beneath the black rubbing cloth, probably won't last long. 5 stars for light weight and pen catcher. Otherwise I would have given 1 star.
Does the job, has a magnet so it stays in its place; it's hardly been a month and the top layer of the erasing-side is coming off at the edges, so probably not the best; but it's cheaper than most, so *shrugs*.
