Seals Well
This sealant works for me. I tried Stan's but it barely ever sealed punctures. Remember to refresh your sealant!

Works great
I know there's lots of debate about tubeless for road, but I have been quite happy since switching. As far as I can tell, I have had just one puncture event, with a hardware staple in 2 spots. Lost some air initially. Rotated the puncture site to the bottom of the wheel and let it sit for less than a minute, and was able to pump it back up with no further air leak.
Not sure what to expect as far as how often I should be "topping it off", but I have done it twice in 6 months. Also, don't have any other brand to compare to. But, found it much easier than repairing/replacing a tube.

No punctures (that didn't seal) in 2,500 miles
Knock on wood, but I haven't had a puncture (that didn't seal) in the 2,500 miles I've ridden on my road and gravel bikes over the past three months. To get an idea of longevity, I sucked the sealant back out of the tires through the valve stem using my injector after two months. I had to top it off, but nearly 2/3 of what I'd initially put in was still liquid. I'd call that a win for both sealing and enduring, which is exactly what this stuff is supposed to do. Win, win.

The Best
My mechanic swears by Orange Seal as well as the good folks at Mountain Bike Action magazine. I made the switch and was able to keep tires inflated that usually went flat in a week while in storage. Used it on a four day, four hundred mile ride at sea level and didn't have to pump the tires up once.

Long-time user of this sealant. It's been reliable.
Using this sealant for my road and gravel bikes for 2 years. Have saved me from many small punctures, works well with plugs if it's a bigger one. Doesn't cause a mess when cleaning and refilling. Haven't use other sealant so I'm not sure how it compare to others tho.

Good overall results
Orange Endurance is the tried and true sealant that won't break your budget. Have had many successful seals occur.
This works so well that you likely will not notice the thorns or small punctures that occur as they get filled.
So far there was only one seal that it could not handle. That was a 2 inch slice that happened when i hit some glass. The tire had to be replaced it was so large.

Sealant not always as marketed
I had a leak in my rear tire that the sealant took far too long to seal. Seemed like a pretty ordinary puncture that it just didn't want to seal. It did do a good job of putting a coat on my down tube. My eventual solution once I noted the tire was near flat was to rotate the tire to the six o'clock position, agitate, and wait. After some time I added air with a CO2 cartridge and went on. After another 20 miles I had to inflate again but at last when I got home it sealed.

Great sealant
Good price and the product actually works. Keep on top of it though adding more sealant during dry, hot weather.

Tire sealant
We have a lot of puncture vine,sheep's head or goat's head stickers around here and this is a must have for flat protection.

Seals good, lasts a while, and easy to clean off
Seals good and lasts a while.
What set Orange Seal apart from some others is that it is easy to clean off when you take the tire off and need to repair a puncture or refill the sealant. It comes off like a layer of laytex; similar to a fake rubber mask that actors use.

Always works
This product is reliable and has always worked for me. I use this sealant for all my bikes from mountain to gravel and commuter. The only time the sealant didn't work was when I had a hole that three dyna plugs could not seal. I also like that it lasts a long time before drying out.

Works well to seal tires as intended.
Orange Seal works well as intended on tubeless tires sealing up any punctures immediately with minimal air pressure loss to tire. You'll need to pull out the puncture object and spin the wheel to seal up the puncture. Wish BTD shipping dept checked and firmly tighten cap as some product was loss in shipment. Shipped with plastic bag around bottle but some leaked out bag also.

It Just Works
As far as sealant goes there is stuff that works and stuff that doesn't. This works great and anything that it hasn't sealed has been pretty catastrophic.

Put it in your tires and don't get flats
Not much you can say that hasn't been said about the best tire sealant available. I've found that OrangeSeal works better than other brands for road tires. Still not always perfect seals, sometimes it takes adding some extra air or a plug but it is still superior.
