Fast and easy way to replenish sealant without all the mess and easy cleanup. My wife prefers this method over using a syringe.
Hack: squeeze the tire before filling the funnel and release once it’s full. This help create negative pressure that draws the sealant in quickly. The funnel is about 2oz., so you can use that to determine how many fills you need.
The Sealant Funnel is probably the best way to add sealant to a tire. Removing valve core, threading funnel onto outer thread, and then pouring sealant is much simpler than my previous method of using a syringe injector. No more "burps" or sealant mess. Small enough to carry in my bike kit. Highly Recommended!
(Full disclosure: Tim sent me a sample Schrader funnel to test before production)
