Review on 🚴 TSI-1 Tubeless Bicycle Tire Sealant Injector by Park Tool: Boost Your Tubeless Ride! by Charles Thomas

I've needed this tool for a long time. While it's easy to pour sealant through a Stan-type injector, bottle, or directly into a removed bead, it's difficult to remove sealant when changing tires, especially if you want to reuse relatively fresh sealant. Unfortunately, the tube does not fit any of the tubeless valve stems I have tested so far, so the sealant cannot be removed from the stem. I tried a combination of Stans and Zipp valve stems (maybe some others). I have no reason to believe the tool isn't great for adding sealant (haven't tried it) but my main motivation for buying it was sealant removal hence the two star rating.
