I was reading the comments over at Deal Extreme for the Seoul P4 star. http://www.dealextreme.com/details.dx/sku.1445 It sounds like people have had problems with them not working or just shoddy construction. Have these problems been corrected? I am especially concerned about the slug not being epoxied or soldered to the star. I will be attempting my first mod (EOS P4) and don't want to waste my time if these are junk.
