Review on Flying Tiger Cycling Tubeless Tire Sealant Syringe Kit with Switch, Presta Valve Core Removal Tool, and Valve Cap - Ideal for Stans No Tubes Sealant and More by Henry Brown

2 stars because the main part of the kit is probably unusable. I have used this kit to insert 2 oz of Stans No Tubes with no problems. However, when I refilled the syringe with another ounce, the tube clogged and I couldn't get Stans to flow through it. Luckily the syringe fits into the Presta valve and I injected with no tubing. Later when cleaning I was able to push water through the hose, it seems the clog was in a small plastic valve on the hose, but without a valve it's impossible to use the hose. Next time I'll just use an injection.
