Review: Don't Judge a book by its cover - While the product package and physical look was very bad (very dusty) and I wanted to return the product, I realized that the product is able to do its job. After few rounds of physical cleaning, the product looks good and able to sharpen most of the knives. Worth the money.
Review: No so good - It is not like they mention no dimensions grinder only two type
