I ordered this mouse through Back Market. It was delivered quickly. Funny to know that it came from Poland. The mouse arrived in neat condition. The mouse has the option of inserting two batteries (AA) for longer usage time. However, this makes the mouse heavier, which I find less pleasant. Fortunately, it also works with one battery. However, this particular mouse is a bit slippery on the sides so you have to hold it a bit more firmly, which I find less pleasant. That may be a personal 'taste' whether that is bothersome or not. Has purely to do with the product and not because it's a refurbished one.
