Use for my road, gravel, and MTBs and have never had an issue. Seals well and lasts longer than alternatives I've tried. Clean-up can be messy, but that is true of all tire sealants that I've tried.

UPDATE: It's been over four months, and I have had zero problems, despite continuing to commute daily on the same route that was destroying my tires. In that time I have added air to my tires exactly once. Haven't needed to add any more of this product, still working great. I could not be more thrilled with how well this is working.Original review:I've never used a product like this before, and I haven't compared it with other comparable products. What I can say is, wow, this stuff really made a huge difference in my life. A month or so ago, my office moved and I started biking to work. Every day I would get a flat tire, or two, or more -- like the day I walked my bike the last bit in to work with a flat rear tire, changed the tube in the parking lot, reinflated it before going home, got a flat front tire going home, and saw the rear tire go flat again later that evening. I was tearing my hair out trying to figure out what was going on. Maybe the tubes I'm buying are no good? Maybe there's a lot of glass or other sharp debris on the route I'm taking? Maybe I'm not changing the tire correctly? Could my tires be underinflated or overinflated? Am I getting the wrong kind of tube? Is there something sharp stuck in the tire? Long story short, now I don't have to care about the answers to any of those questions because after pumping an ounce or two of this stuff into two fresh tubes, I've had zero problems. In fact, last Friday I was riding home and noticed a weird sound that turned out to be made by a chunk of glass embedded in my front tire. I pulled it off and immediately heard the sound of air escaping. So I ignored it and kept going, and after a few seconds the air sound trailed off and stopped. Got home and checked the pressure and it was 100% fine, and continues to be fine. I haven't changed a tube at all since buying this stuff and using it once, and both tires are holding pressure very well. My bike is my main means of transportation to and from work, and it's also just about the only exercise I get, so it's really been a lifesaver for me. Plus I learned that Schrader valves have cores, and how to remove and replace one, I had no idea, I ended up using some largeish tweezers to unscrew the core and it worked great, much less intimidating than I thought, 100x easier than changing a tube even once let alone multiple times a day.

This little bottle was perfect for the one bike. The little nozzle makes filling through the valve stem EZ-PEASY. I keep the little bottle around and refill from a larger bottle now. A+ product.

Have yet to have a failure with orange seal, have ruined several tubes and had other sealants, this one is the best

The product does what it's intended to do. Easy to use. It would be helpful to have markings on the bottle to know how much you've added to your tire(s) or the amount of liquid remaining.

While on a road ride, I suddenly felt something spraying on my right leg. Stopped to see that it was sealant. Found the puncture, which had bubbles forming. Got back on and rode slowly for about 3/4 of a mile and then checked again. The tire still felt relatively firm and there was no air coming out of the puncture!Couple of weeks later I finished a ride and saw dried sealant on my frame (which I'd cleaned after the 1st puncture). This told me that the sealant had fixed another leak (or maybe the original one started leaking again).This stuff WORKS. I did replace the tire and bought another two containers of the sealant. No way to know how many tiny punctures may have been sealed over the past year that I've been using this product.

Tubless tires are amazing.I go months without a flat when I used to get them regularly.They're a bit of a trick to get good at installing but after they're installed; you can forget about them for months.A few hints:1. Get a high-flow air compressor. It's necessary to have a burst of air to seat the tire beads properly.2. You must ride newly seated tires to get the sealant to seal up the tires to the wheel. Otherwise, the sealant sits at the bottom not reaching leaks.3. You must check your sealant levels regularly. If you start to lose air, it is likely b/c your sealant dried up and needs to be replenished.4. Don't use power washers on tires using sealant. It forces water inside your tires and ruins the sealant. (And ruined a race I was in last august when the tire wouldn't seal b/c it was full of water.)5. Get a CO2 canister with a regulator and keep it with you. There are certain circumstances where you'll 'burp' air out of the tire as if you have a hard landing or a gully and the tire rolls over a bit letting air slip out.There are two types I have used. This OrangeSeal or Stans Tubeless.Both seem to work well but they're quite different.1. Orange Seal is more of a latex that coats the inside overall. It's a bit like a rubber surgical glove for the inside of your tube. It's a pill to get out but it is possible to peal it out like with sunburned skin.2. Stans is more of a sealant that works by clogging holes with a pancake batter fluid. It's a little easier to clean up but takes some work.Either way, tubless tires are a real advancement away from tubes.No more thorn flats and other small holes but slits or pinch flats will still happen. (Although I haven't seen it.)

After adding the sealant to my Hutchinson Touareg tubeless tires with presta valves, I added some some air and all of the thorn-made holes bubbled and hissed for a moment until beautiful silence. That was last week and I haven't had any issues with a slow leak or losing psi beyond normal.

Reasonable price for an above-average product. I haven't used it yet but am glad to have it packed for long distance journeys.

Terrible sealant. A mere 4 days after buying this, my bike was stolen!Just joking... It seems to be great sealant. The slow leak disappeared after the easy injection process.Now I just need to buy a bike to go with my remaining sealant.

Quel plaisir de crever sur une vilaine épine et de regarder le préventif gicler puis progressivement colmater le trou jusqu'à pouvoir réajuster la pression et reprendre la route sans plus de prise de tête que ça. Préventif le plus efficace testé à ce jour.

This sealant worked first time with a new set of tubeless rated Continental X King tyres which had several pinholes in the sidewall. This was discovered when I received a fine spray of the sealant in the face when inflating the tyres to about 40psi.
