Public service announcement: if you don't have one of these Engineer SS-02 solder suction devices, go buy one now: https://amzn.to/3V4ofAm
If you do have one, you've used it for a while, and it doesn't work as well, gets stuck, etc: unscrew the tip and clean that sucker out. Mine was so nasty inside, works like new now. 🤢😁
