Query: Terrible threader

I bought this for the self-threading feature, don't bother. I got it to work once and didn't even know it. I'd been trying a long time, gave up and went to bed. In the a.m. got up to try some more, asked my husband to have a look. He said it was threaded. Used it till I needed to thread again, still can't get it threaded with feature. The light is worthless and I can't seem to find a position for my own light that helps to see what you're working on. It's a big dissapointment.
