I bought a huge amount of it on sale - initially thought that I had made a terrible mistake (use it in my Janome MC11000) as the thread would shred when I was loading my needle. Figured out somehow that if I don't use the tthread cutter until after the needle is threaded it stopped that issue. Also, it seems to tangle if I have the thread on the machine thread spool. I now use one of the table top thread holders and the tangle issue is no longer a problem.
