Review on 5pcs/set 900M-T-K Soldering Iron Tips Soldering Bits for Enhanced SEO by Brian Nelson

They seemed good and worked very well the first time I used them. Although the heat transfer really left a lot to be desired. But after two or three accidental uses, things get corroded as hell, and one even melted and bent. Typical Chinese bullshit.... Great if you just have a small project and it's going to sit in your garage for years, but that's sorely lacking if you intend to use it regularly...
