I bought this intending to use it, but I never ended up using it even once. I think it's a good product, as it has a 4.5-star rating. It's new and unused, but I did take it out of the box once to check it, and there's a slight stain on the surface of the box from the beginning, so please refrain from purchasing if you are concerned about this.
