I'm only giving one star because I can't put a zero. These tips will burn out 24 hours a day, 24 hours a day, even with tin baths and constant cleaning. Weller used to be number one in that department. but no more, i get better results with a $20 iron. I buy them for WCPT models, we don't use them anymore, we've used about 10 of them. Now we use AOYUE brand irons.
