I didn't have high expectations for this ridiculous product but I was still disappointed. Those pathetic plastic things are there to save you a few minutes of soldering, not to save you. It's a huge hassle to attach them correctly, using little latches that tend to break, and just attaching tin connectors and then realizing that none of that works anyway. The conductors don't connect, the circuit doesn't close, and yet this is an old soldering iron. Except waste of time and money. Absolutely not worth the effort.
