Review on Weller D550 Soldering Gun Replacement Tips (7250W) - Pack of 2 High-Quality Tips by Lamar Vanderburg

I ordered 2 soldering gun tips but got "100 super sharp (razor sharp I think) blades". Haven't received the soldering tips yet but I'm sure the tips and blades will be quite suitable although probably not interchangeable. EDIT: I finally got my hands on some soldering tips. They were correct and intact.
