Flat Out QuickStrike Tire Sealant Off-Road Formula - Prevent Flat Tires, Seal Leaks, Contains Kevlar, 32-Ounce Bag

Great investment. Better than Slime by far. I've already experienced how dependable this product is. I got home. Opposed to having to repair inner tube on the side of a highway. Truly grateful for that. It gives me confidence to have this in my inner tube. I've heard concerns about weight. That is MUCH LESS a concern for me. Besides, I do not notice any difference. I honestly recommend this product. Experience has SHOWN me. I can trust it to work as stated, when needed. And Get Me Home!! I'm using this in my Ebike tubes. Bike weight 112 lbs. My weight 240 lbs. And it STILL held up and got me home. At 35 to 40 mph.

I have two ebikes, and used to get flat tires all the time due to the amount of goathead thorns that are in my area. Since adding Flat Out to my tires, goatheads are no longer an issue. I even had a 1"x2" piece of metal pierce one tire, and while it eventually went flat, I was able to make it all the way back home (over two miles) before it did. Another time, I picked up a 1/4" wide by 2" long nail, pulled it out, and kept riding back home, and that tire still hasn't gone flat. No patches, no hassle—this stuff just works! It can't stop all flats, but it will greatly reduce the number of them you have to worry about. I highly recommend Flat Out!

BEST THING: this seems like a practical thing to keep around for off-road or utility tires where flats are a real problem. I like that it is meant for heavier use and not just a tiny emergency fix. It gives some peace of mind having it ready. WATCH OUT FOR: I would not treat it like magic for every puncture. Follow the directions carefully and make sure it fits your type of tire, especially if you are dealing with tubes.

Cap was loose and lost a little. Amazon should use a box on this, not a bag. Other than that, good product

The product is really good. But I got this in a bottle like I ordered and a plastic bag in a shipping bag so since they shipped it that way, there was no coverage for the bottle so it came to me leaking in the plastic bag I ended up sending it back in a box like they should’ve done in the first place on top of that I had to spend three bucks to print a label. My Friend bought a gallon of this from them like I said the product is great. They just should ship it like they should ship it in their box. I gave them five stars because the product is excellent but shipping I’d give them two stars maybe by seeing this. They’ll do a better job in shipping.

The top was loose and it seemed some product was missing, I tried to use it that way and got as much of this on the floor as you get into the tires. The first tire wasn't as bad, but it clogged, so you need to remove the top and try to twist it back on and it never becomes fully tight, it can twist back loose as soon as it feels a little tight. You need to do this over and over too to unclog the actual bag itself. The second tire had me doing that at least 20 times, used abut 50 paper towels, the stuff is slippery and gets all over your hands, the valve and floor, lots of cleanup. I hope it at least stops leaks after all that work. I do not recommend this bag style after I went through this mess, ity seems defective. Watch some videos and it seems easy enough, but they never show you the second tire or the cleanup or clogs, so the instructions seem simple, but the reality is a lot more than that.

Based on all the positive reviews out there about this product, I used this in my fat tire e-bike as soon as I bought it. I don't know how many flats I would have had, but I've ridden over 1,000 miles without a single problem. Maybe I'm lucky, or maybe the product works like a champ. Either way, it's great insurance against a flat tire - one of the worst experiences in biking. Some people say it's expensive, but it's actually quite the opposite. I think the people that say that haven't had to replace their original (cheap) innertubes. I just bought good innertubes from Kenda and they were $24 each, which makes this a no-brainer. It's guaranteed to last 10 years - that would be at least 40,000 miles for me, so basically the life of my innertubes. It's not at all messy to install if you follow the instructions. A block can happen occasionally, but it's really easy to clear and continue filling. I've only used the bags and not the pump, so I can't vouch for the pump either way. But since the cleanup is water and a paper towel, installing this in your tires is nothing to be afraid of. If you have a clog, stop and clear it before putting excessive pressure behind it, because I can see where that would cause a mess. Just disconnect the hose and take care of the problem, reattach the hose and continue. I think I had to do that once during the installation of two tires. Again, I'm using the bag and not the pump. I expect it to function as designed since I've seen youtubers doing tests for functionality and it definitely works. It's great peace of mind when you're miles away from home and there's almost no chance of you getting a flat tire.

This stuff works great!

Good

Purchased this for my fat tyre ebike. Very easy to use, half a bottle in each tyre 26x4 inch. Hopefully it does what it claims. Flatout must be confident as they offer a free tube replacement if the product fails. Piece of mind for long distance riding 🫡

Really like this. Far as I know it's not been called upon but who can know for sure. Anyway, it gave me the confidence to go riding in the woods a little more. I think I am OK to trust it, I really hope I never get any more punctures...EVER!

Failed to seal two pinholes on a defective e-bike new inner tube (or which I accidentallly pinched). Any excuse that the sealant failed to spread before riding is invalid because I always massage in before fitting to wheel. So I patched the first hole, to find it lost pressure again leaving left a wet hole obetween the inner and tyre n the second pump! It appears either not to work at all or takes too long to seal. I have kept the sealant in the tube after the 2nd patch, but have very little faith in it. Always carry a spare inner!
