Updated 2023: Im now on my 4th bottle of this stuff and increased the star rating. Ive got it in all 4 lawnmower tires, both tires on the lawnmower trailer, and in the wheelbarrow tire. Ive never had a single leak since. We've got a lot of thorns in our yard that are hard to see and I'd had my fill of patching them. After seeing how well this worked on the lawnmower, I keep putting it in any yard tire that gets a flat and they all hold air permanently from then ok. The product 100% works as advertised. I still think its pricey (but saves you on time dealing with future flats) and still hate the cheap stem removal tool (luckily I saved the metal one I bought when the original broke on me). I also hate the new container - it refuses to stay upright. But the product itself works so well that its worth overlooking all of these things. Original review: Used in a lawnmower. Have some thorns on the property that occasionally puncture tires, so I often have at least 1 tire losing air. Used to pull and patch, but thats a pain to keep up with. Tried this for a plan B to hopefully stop the constant patching and so far its holding up great after a month. Easy to put in the tires with the instructions. Two downsides: -Cost is a bit high considering usage. I didn't read carefully before ordering, but it takes 1 bottle for the 2 fronts + 1 bottle for each rear. I haven't bought it for the rears yet as I'm reluctant to spend that much more money. -The valve stem remover included is absolute garbage. It barely removed the 1st one when it cracked. Couldn't reinstall the 1st or remove the 2nd at all as it disintegrated. Had to go buy a metal tool from the store mid project. IMO they shouldn't even include it if they're going to out such a cheap one on it.

Flat Out Keeps Our New E-Bikes Rolling! We recently purchased a pair of e-bikes and are thrilled to hit the trails! Being new to e-bikes, we also wanted some peace of mind when it comes to flats. That's why we decided to try Flat Out Tire Sealant for the first time. So far, so good! Installing Flat Out was a breeze following the instructions, and it only took a few minutes per tire. We're happy to report that after riding approximately 250 miles, we haven't encountered any flats yet! Here's what we're loving about Flat Out: The product claims: Fewer roadside repairs. No one enjoys fixing a flat, especially on an e-bike. Flat Out hopefully means we can spend less time tinkering and more time enjoying the ride (and we have for 250 miles so far!). Increased confidence: Knowing the sealant is there offers some peace of mind, allowing us to explore further without worrying about flats interrupting our adventure. Long-lasting protection: The product claims to last for over 10 years, which is a great value. We'll be sure to update this review after even more miles on the e-bikes, but with 250 miles under our belt and no flats, Flat Out seems like a great way to help prevent flats and keep our e-bike adventures rolling smoothly. We recommend it to any new (or seasoned) e-bike rider looking for some added puncture protection!

This is a great product. I had a flat tire in the back tire of my electric bike. Which has a tube in it. I used this product cuz I just didn't want to take the tire off took a chance. That was over a month ago tire still holding up great with no problems. This stuff is very thick so it takes a little bit to get it in.

Easy to install , I haven’t used it a fat tire E bike and mostly ride trails so-far I have not had any flats while using this product! I recommend it for fat tire bikes that have relatively low tire pressure 20 lbs . My neighbor uses this also he got a stick that punctured his tire it did not go flat he was able to make it bake to his house! Works as advertised!

I've bought this product multiple times, the packaging used to come in plastic bottles, worked great. Now the only one I could find is this bag. The tube to pull in and out of the cap was so stiff I needed to use a pair of pliers and the cap didn't even seal so the product leaks out as you squeeze it to fill a tire. Bring back the old containers. No complaints on the sealant itself.

Such a great product I ordered some for all of my tires that are giving me trouble.

It does not seal inner tube punctures.

Works very well for electric scooters!

#####The Ultimate Anti-Flat Miracle for Delivery Riders and Cyclists##### Look! if you really wanna know what kind of product this is, read this carefully — this is my honest conclusion after using it for a whole year. almost everyday about 10 Hrs biking as a food delivery. I moved to Montreal last year, and around this time I started doing Uber with my e-bike. Everything was fine for a few months, until one night I got home and the next morning I saw my rear tire was completely flat. I was so disappointed — I couldn’t go to work and I had no clue where to even take the bike. The closest repair shop was a 30-minute walk away, and I had no tools, no idea how to take the tire off, and no car. So I literally pushed my bike all the way there. And trust me, my bike is heavy. After that, I did a ton of research on how not to get flats again. From changing the tire and tube to using tube liners. Tube liners are a good idea but honestly the good ones cost like $200–300, and people say they make the bike slower or get thin after a while. Then I found this product and decided to try it based purely on user ratings. And let me tell you — for someone like me who works 10–12 hours a day on the bike, a flat isn’t just annoying, it’s a major problem. That’s why this gel is a game changer. I went to the repair shop, asked them to slightly deflate my tires, and then I started injecting the gel into the tubes — one-quarter bottle per tire. The next morning while getting ready for work, I saw a small wet spot on my front tire. I thought, “This isn’t water… what is it?” I touched it and yep — the tube was punctured and when I pressed it, the gel came out! I was honestly scared and disappointed. Because look, every time this happens, not only do I pay for repairs, but I might lose an entire workday if I don’t notice the flat early in the morning. One time it happened on a busy Friday afternoon and I couldn’t find anyone to fix it for the whole long weekend. Huge financial hit for me. So I told myself, “Okay… the gel is leaking, the tube is punctured. It’ll probably deflate by the evening. The gel is just buying me a few hours to reach a repair shop.” But something inside me said: “No, just go. See how long it lasts.” And I swear on everything — what I’m saying is 100% true. It lasted 7 or 8 months. Seriously. Until about two weeks ago. I started work one morning and after maybe 30 minutes I noticed the tire was slightly losing air. Seven or eight months! Maybe even more! I bought it with my brother-in-law’s account so I can’t check the exact date, otherwise I’d tell you exactly how long this little beast held up. When the repair guy looked at the tube, I showed him at least 4 or 5 holes and he couldn’t believe it. Sadly, I accidentally deleted the photos when cleaning my phone storage. And here’s the funny part: the night before the flat, I had just ordered two winter tires. The next morning — boom, flat. I was so annoyed because until the new tires arrived, I had to ride with tubes without gel since I wanted to save it for the new ones. Basically a whole week with zero protection. A week? Well… that morning I fixed the flat, and that night I delivered my last order with another flat! Yep — two flats in one day because I didn’t inject the gel in the morning. I thought the tube could survive a week :)) The next day I had no choice but to inject the gel into my front tire until the new ones arrived. That’s the front tire story. The rear tire story is a bit different. My bike is heavy, there’s a bag on it, and all my weight is on the rear tire. That one only got one flat all year after using the gel. And the second “flat” wasn’t even really a flat — I heard a tiny sound from the back while working. I checked and saw a whole screw stuck inside the tire. And I didn’t feel any air loss at all! I only went to the shop because of the sound of the screw scratching the asphalt :)) If you’re seriously looking for a miracle for your tires, this is it. This product literally saves my income. I even have a brand-new bottle at home ready to go. I’m not going anywhere without this gel. Big shoutout to whoever made this stuff. Oh, and by the way — there’s an Indian mechanic around here who does mobile repairs. He totally hates me now because I told my friends how to avoid flats :)))

SENSATIONAL!!!!! Waited until I got a flat to see how effective "Flat-out" product is. Wasn't too long till I had a flat. I put the "Flat out" in as directed inflated and away I went, INSTANTLY. Tyre has not gone down in over two weeks so looks like this product is actually MAGIC. Can't recommend product enough.

I must admit I was sceptical about purchasing this item to fix my ride on lawn mower tyre but it is brilliant. That good I will be buying some more.
