Mine didn't work with Ultrium 2 drive
on May 19, 2016
Problem with these is that they do not say in the documentation which ultriums they support. The one we received about a month ago works for Ultrium 3, 4, and 5 drives, but does not clean Ultrium 2 as advertised. Do not have Ultrium 6 or 7 drives so can't say there. Either Amazon's description is old or we received a one-off; I can't tell because nothing on the tape or labels indicate.
For the record this is the first time I've seen compatibility issues with different gen drives when it comes to cleaning cartridges so I'm pretty nervous now about ordering in the future.
