I just purchased this machine after my older singer (50 years old) had the bobbin winder malfunction. No one knows how to fix this. Automatic bobbin winder was a dream. But the automatic needle threader is a nightmare!! I tried for 40 minutes to thread it automatically and gave up. I threaded it myself. If not for this "feature" I would love the machine. I did notice that the bobbin thread sometimes skips. Thankfully I'm not doing any heavy duty sewing.
