So much better than using a bottle and tube!

Eventually, the bottle's top and tube get clogged up. It's also a lot messier when the tube isn't all the way sealed. This funnel saves me time and sealant. Game changer!

Thought it wouldn't work, but it does!

Saw this mentioned on James Huang's N-1 newsletter. First thought was "nah, that won't work" but then saw James' experience with it and thought, well, okay, guess it does work. Ordered one up to support another maker, got it quickly. Nicely packaged, and the print quality is top notch.

I will warn you that it is smaller than 2oz so if you try to dump your whole 2 oz bottle into it, you're going to have a bit of a mess on the floor. Not speaking from experience or anything. 😆

Once I took it slow, it works exactly like you'd want it to and is quick and easy. Certainly way easier and quicker than a sealant syringe, and like James pointed out, cleanup is also quick and easy, just a rinse in the sink and it's good to go.

Highly recommended!

Simple product that does the job

After having used scoops, syringes with tubing, etc. This funnel makes it super easy to do a tubeless setup, as well as do routine maintenance. Way less cleanup than my previous methods.
