Review on 🔧 Stans-No Tubes Dart Tool Refill: Pack of 5 - Practical and Versatile Solution for Tubeless Tire Maintenance by Alex Webster

Worked once and failed 5 times. You feel like an idiot putting so much time into getting them working. Just won't work on MTB tires with small punctures that the sealant won't fill on their own. Worked great with the big hole but the sealing webbing rips off the smaller holes leaving plastic spikes rattling in the tire and the noise is driving me crazy because bike noise = power loss in the biker's head. Save a few strips of bacon for small holes, or go wild and poke with an Allen wrench first to make the hole bigger.
