Mine is a Juki... I do have a needle threader a little bit like yours on my Brother embroidery machine though. But it's still different, it has fewer things to wind the thread through.

I *LOVE* the Juki's threader. I just hook the thread through that little clip, then push a lever. One hook pulls the thread down across the needle's eye, while a tiny hook pokes through the eye, grabs the thread, pulls it all the way through the eye. It works on all normal threads and all needles size 10 and up. Struggles with sz 8 needles.
