Bests & Worsts Reviews from Amazon

I don’t like this at all. It picked up very little dust and turns my fingers blue after use. I tried to wash it off but it is still blue after washing it with soap and warm water. I have purchased a different brand before in yellow and that seems to work much much better. Also this thing leaves some residue behind, not a clean wipe as shows in my picture. I bought it because of high rating but not sure how it gets such high rating??
