I have easy access to the traditional liquids and the Quickstix and still use both of them.
You can't use the Quickstix in blind holes since the application technique is different. So you dribble the liquid in the female hole.
When working on bikes or just about anything else, I use the Quickstix now.
I like them because they don't drip, less mess, you can apply the material to all of your bolts at once assembly line style before you use them, the material doesn't drip off, and they fit easy in my toolroll.
Anaerobic materials like threadlockers will stress crack certain types of harder plastic faster than you can spit if drops of product get on plastic surfaces. Anaerobic materials can also remove the shine from certain types of harder plastics when drops get on a surface.
Peace love and glue,
