They come out to about 21 cents per bobbin. I would have had to buy empty bobbins and wind them so for me this was a good deal. They're wound very full and my machine loves them.
So far, I've only used the #90 thread that came with my machine. Luckily, it uses the same bobbin as my Janome and other Brother. Winding the bobbins doesn't bother me. For my regular machines, I usually wind two or three at a time. Good to know the pre-wounds work well, though! I may break down and try them, in the future.
