How: There is a wide range of stamp sizes, some of which I will never use, but the ones I have used more than made up for the purchase price. I don't have to drill too big holes to align the screws. If I work in an industrial setting and need more durability I would probably buy a more expensive set. You are great for what I do. Dislikes: I don't know, I've just started using them so we'll just have to see how long they last.
