Has anybody tried the Titanium coated machine needles sold by Superior Threads please, and if so, what did you think if them? I am aware that these have been available for long arm quilters but are now coming onto the market for home machinists. I don't have a long arm, so have never tried this type of needle.
They are more expensive than other (non titanium coated) needles, but it is claimed that they last five to eight times longer.
