i bought such a device on a second hand market
it ruined severall tapes becouse it contains a real magnet in side.
other cleaner tapes realy clean OR have a mini pcb
NOT this one it has a REAL MAGNET ABORD
now i wonder how many original tape were damaged by this "cleaning tape"
so what went wrong?
it has NO CLUE on the casste ;abel NOR the box that it is DANGEROUS fore your magnetic tapes
just a SIMPLE REMINDER would have alerted me... but
i did store this cassette next to the tapes, since those "belong " to each other...
and its "Non-Abrasive"
but this is not a "device"
nope
its a "magnet on a rope"

so do NOT store it next to your tapes
its 40 years to late to warn the original users, i bougth it ?? 10 years ago??
