The funnel has all the potential to be fantastic, but the negative pressure inside the tire prevents the flow of sealant into the tire. Try doing the burping procedure and it makes a mess even if it is done slowly especially on smaller volume road tires. Larger MTB tires are better. I am going to try to use a aerosol can spray straw to see if that makes it better. This will also work as a dipstick
Thanks for the review Eric. Negative pressure can be an issue and I'd recommend squeezing the tire and holding it before adding the sealant to the Funnel. As you add sealant, slowly release your grip on the tire and the sealant will draw in. Thanks!
Works great for my specialized tubeless valve stems!
No mess, no fuss and simple to use. I've purchased four so far and given several to my friends as these little funnels make for a simple sealant fill in the shop or on the road. Just plain works great!
Works great. So much less mess. Feels a tiny bit more expensive than need be, but this will last me the next 30 years, so maybe not. I definitely needed the version that works on WTB valves, good call!
Great funnel for a clean fill and top off of sealant. Much easier than a syringe or popping a bead for sealant filling. No more sealant dripping on the floor.
