I have a Designer one and the needle threader only works for me if I use "top stitching needles." They have a bigger eye. Also, I never fill a bobbin with the machine threaded thru the needle and always slow the speed down when filling the bobbin. Husquvarna machines are known for filling sloppy bobbins. You have to do all you can to help them. My bobbin also dances around in the bobbin case when I sew and the noise drives me crazy. Haven't found a solution for that yet. Loosening the tension doesn't help.
