BR Verbatim attention that these are organic technoogie (LTH) ... which leads to two problems: 1 - Not compatible with some "old" BR burner (including plextor 920sa) 2 to 1 life totally ridiculous compared to them verbatim HTL which are superb products. (Lifetime of LTH: 250h, life of an HTL: 2000 hours)
My advice: if you see LTH, it is certainly cheaper but prefer other non reférences LTH verbatim!
