Query: A Pig in a Poke?

I bought this thing without checking the pin specifications thinking that it came with standard sizes; no one to blame but myself. Buyer beware; this might not fit your snap rings.Pros:1. Easily intercgangible heads for internal/external snap rings.2. Inexpensive with adaquate quality and suitable utility for occasional use.Cons:1. No tip size specifications at amazon.com.2. No information at Irwin WEB site.3. Only one 180 deg tip size works with standard 1/4 amd 3/8 inch snap rings. This severely limits the usefulness of this tool. I can just see myself with a jeweler's file reducing the size of the others...4. You can injure your fingers opening the package.5. Needs a storage case (Michigan Industrial Tools has similar pliers with a case).Sugestions:1. You can use the inner molded plastic packaging for storage.2. Irwin needs to provide a variety of heads with tip size specifications.
