Fantastic Sealant

I picked this up after watching a review of it online. It was my first time setting up my tires tubeless, and found that the packaging Muc-Off uses makes this super easy to use. They even include a clear portion of the back of the bag with measurements so you can ensure you're putting the right amount of sealant in. I've put some miles on it so far and had no issues at all

Good So Far!

This is a difficult product to review. I've used another brand of sealant and had some flats as the sealant wouldn't seal the puncture even though it was very small. Since I've used the Muc-Off sealant I haven't had a flat so I guess either it's working or I've just been lucky to avoid any debris that would cause a puncture. I haven't seen any of the purple liquid on the outside of any of the tires. I'm not a fan of the pouch as it's difficult to add a specific measured amount.

Only stuff I would use

The tubeless sealant goes beyond what anyone could have told me. I could go on all day on the good.
