Input:
I purchased several sets of the Maxell 9 hour tapes last year and these tapes are the worst I've ever encountered.  Initially they worked fine (for about 2 months), however, after repeated use they now fail constantly. I'll activate a tape to record only to discover later that the tape has has stopped recording after two/three hours of recording & it has triggered my video recording machine to stop and shut off.  I've purchased at least 10 sets of these tapes and out of 30 tapes only 6 or 7 of them work as they should.  I've cleaned my videotape recorder's head and still use the Maxell tapehead cleaner so it isn't my unit that acting up it's these Maxell 9 hour tapes.  Many of them seem to stretch when I'm recording so they are unusable because too much tape wound on each reel.  I am just disappointed in these purchases and the money that I wasted because now I'll have to purchase new tapes still, but I betcha they will not be the Maxwell brand tapes...  I do recall there were many negative complaints about these tapes, I should have listened!
