Review on Pack of 6 Soldering Tips Compatible with Weller ST Series for ST7 WLC100, SP40L / SP40N, WP25, WP30, WP35 Soldering Irons by James Wickware

High-quality soldering tips, fit easily on my weller and normal soldering iron. Glides straight but firmly so as not to wobble. Some tips have a hole in the bottom, I assume this is for faster heating (maybe other reasons, but I've noticed they heat up faster). The original tip that came with my Weller station lasted 4 years so I'll be back and updating this review in 4 years time to see if the one I use the most holds up to this package!
