I wanted to take them to solder. I haven't used them often, but they have a good tip. Happy with the quality. I don't solder for life so they should last a long time.
Pros
β The soldering tips are made of imported copper oxide raw materials, special molding machine is used for processing, the size of the soldering tip is very accurate. Fine-grain lead-free alloy electroplating, very long service life of about 3-4 times compared to household products.
