I bought a 100 pack of these last year. They aren't TY, but I felt the media quality was better than the typical FAR CDRs (i.e. Spin-X or E3Works from OMax recent deals).
My spindle was rated at 40X but I believe my Lite-On 48X burner sees it as 48X media. OTOH, the E3Works 48X media only registers as 32X speed (and I don't bother to force a higher burn speed).
