I have three machines with auto threaders. The best one I have ever used on any machine is the one on my Singer Quantum. It works first time every time and that machine is almost 10 years old. My Janome auto threader works when it wants to. The expensive Brother may work just fine if I could figure out how to use it. The dealer didn't know either! It's different then the models she had in her store and she wasn't all that gifted in the how does this machine work category. (her shop went bankrupt.) I use a magnifying gooseneck lamp and it works great for me so far.
