Carls ST 0.5x wide angle lens w/macro attachment

Anyone heard of them or know anything about them or their prices?

Seen this around and wanted to get a present for my daughter, as she really loves photography. She's about 15 years old and i got her a Canon 1100D for her birthday. She's really passionate about photography. I decided get her a lens, but not that expensive types. Well, she's still learning, and i believe in giving her the tools and she have to earn herself to get what she really wants. She can want this and that, but earning what she wants is a valuable lesson. It will help her. Back to the main story, Carls ST 0.5x wide angle lens with macro was sumthing new for me. Im not really into photography and its stuff, but that could be what im looking for, as a present for her grades. There's a funny article for those looking for the same information, but that site provides alot of helpful information about the difference between the magnification value, and more.
