Vinpower makes and sells duplication equipment. They also buy media from a number of manufacturers and put their brand name on them. At that price, you can be sure that IF they are actually made by Taiyo Yuden, they are the TY value line B grade discs. Normally range from decent to don't bother. If you are interested in trying T-Y's, you would do better to spend the same money on their premium discs.
