I have some and they've worked fine but right now I'm really mad at Harbor Freight. I'd ordered 20 pkg back when they were $1.49 a package. Then I got a card in the mail saying that they were on backorder. Then I got another card saying that if I wanted to keep them on backorder to mail the card back in which I did. They cancelled my order anyway and now if I want them I have to pay $1.99 per package!!!
