Even though the insertion tube doesn't fit all the way in to my current stems, I can already tell that the sealant syringe will be a welcomed addition and $12 well spent. It takes the guesswork out of dosing, it's easy and it's relatively clean. I did have one instance where I hit some resistance when injecting - rather than push harder, I pulled back on the plunger and tried again and I got smooth sailing in return. After filling the tires, I flushed the tubes/syringe a few times with some warm water and took it apart to let it dry. Good stuff.
