The 4 star there with me, therefore, only for a very important point of criticism: Especially in the last year and a half have repeatedly crossed my tapes that were not wrapped completely clean, that is, in part, to loosely superimposed on the coil. That can quickly lead to Bandsalat depending on the used recorder and the aggressiveness of its mechanics. The risk of this streamlining effect has been known for years, why bands before shots are usually durchgespult once. However expected to lack of time the band changes, so that the tape must be "fresh from the OVP" recorded, you can experience in the post with DV Premium unpleasant surprises professional tapes are here just clearly the additional cost worth.
Another, smaller deduction must be made in the cases: Their plastic is not as strong as the beiweitem many other manufacturers / Series (mainly Panasonic, PQ, SQ, AMQ), so the shells shatter easily. While you should never mechanically load cassette shells, but just travel filmmaker and his associates know that the reality is different from fast.
In itself, therefore: reliable tape with a bit more delicate shell, in which necessarily Spuldurchgang is recommended.
