Stan's the Man

This is my first time using Stans sealant, and I'm glad I've switched. I punctured a MTB tire this weekend and realized I had zero sealant in the tire to stop the flat (pro-tip: check your sealant level BEFORE you go riding). Back at the car, I loaded up with Stans (via the syringe method), pumped up the tire, and Stans sealed the puncture. I was able to get back out and ride more miles without a hitch. This is my new go-to for sealant. Thanks, Stan!

It's Stan's.
I've run Stan's since the days of "homemade" tubeless wheels. Be it cyclocross, gravel or MTB, I've only had one unrepairable flat during that time, and, ultimately, I think I may have been the rim that one time. Due to the circumstances surrounding the flat, I couldn't determine if that was the cause.

Works well; hard to pour
Great seal on the go! But the hole in the top to enable pouring does not line up with the long axis of the package so can't use it for easy pour.

It's the best. The original.
Yes, many brands try to copy Stan's but use the original. I've punctured so many times this winter and just as I'm panicking it stops. Top off with CO2 and I'm back to my ride. Every time it happens I think of tubes and when I used to have to strip the dirty, salty tire off. Thank you Stan for such an amazing invention.
