I like the product and it works. it didn't seem like it had a lot of paraffin on the mop part (smell test), but it did pick up the dust and cleaned it well. At first there was a minimal amount of red fibers that shed, but now it is nearly insignificant. Overall a non-issue. The supplied cover works fine, but it doesn't really fit all that well with the product... I dust off at red lights and I clean and then spray dressing on it to keep the plastic looking matte shiny and black.
