Review on 🔧 Effortless Application: Stans No Tubes 2-Ounce Sealant Injector for Hassle-Free Tire Sealing by Tom Motko

If you have Presta valves, look elsewhere. All 5 star ratings are for the previous brass adapter version of this product. The latest version of this product comes with a plastic adapter that is poorly molded and CANNOT ATTACH TO THE PRESTA VALVE. After removing the core, I tried threading the adapter onto my mountain bike's Presta stems. The adapter just doesn't fit making this product unusable. I was going to return mine and exchange for another injector but apparently the seller doesn't accept returns. Just stay away from it.
