Maybe two stars will turn someone's head, I found that generous, uh, undeserved. When I was a ridiculous newbie to soldering, I bought this tip from B+D, the seller of the items listed, for a 35% discount. I didn't know any better. Now that I'm considering becoming a volunteer or victim of a component that, apart from the name Hakko, has to account for 99% of the cost, gain, loss, anything close to technical, or as far as I can find , a subject about which virtually no information is available.
