It was easy to use. I used it on a new and an old tire for my 4 wheelers that wouldn't hold air over night. No longer an issue after using this stuff!

I have a riding mower which frequently travels over big thorns. I'm pretty rough on the tires and the front tires always get leaks, both fast or slow. A tube wouldn't solve the problem, because it would soon be pierced. 5 oz of this in each front tire solved all my leaks. At least for the first month. I also like the "watery" consistency which made it easy to use, and hopefully won't gum up the rim like some other products appear to. Very happy.

Best product on the market for off road use tires. Easy to use, easy to remove out of tire when needed. Packets are perfect size for atv tires and smaller. Contents works really fast. The only negative I have is: it is a liquid form and have to be careful pouring it in to the Syringe it spills very easily. With the small containers it would be nice to go straight from the bag to the tire. No mess

As my title says, this stuff worked better than I thought it would. In fact it worked so well today I will be ordering more.

I say today because how can you tell if something like this is actually working... never getting a flat for years? In other words, if it fixes a flat before your eyes it works, otherwise you really don't know.

See I had a lawn mower tractor that developed a real bad tire leak a couple of days ago. The way it happened was I cut a Russian Olive tree down, if you know what one of these trees are like, you already know why I got such a bad leak. These darn things have thorns that can get to be almost as big around as a pencil, and are just as sharp as a needle. Moreover, these spikes as I call them, can get to be 3" to 4" long. In short, if you run over one you will have a flat tire, period. That is unless you have this stuff inside the tire already.

To make matters worse, if you run over a branch from this tree, you won't only get one or two thorns/spikes stuck in your tire, because as you drive the branch bends easily (only the spike are ridged), so before you know it you will end up with a half dozen of these spikes all the way around your tire, as if the whole tire has a new tread made up of a Russian Olive tree branch. Trust me on this, it will happen just like this.

After pulling a half dozen 2" to 4" inch spikes out of the tire, I knew if I took it to a shop they would require me to put a tube in. With this inflation that isn't supposed to be an inflation going on, I'm sure it has made tire tubes today cost almost as much as the whole tire cost me just a couple of years ago. So I thought I'd put this product to a real test... I already have some in my John Deere 2305 tractor.

Honestly, it shocked me how quick it worked. It worked so fast I didn't even need to add anymore air to the tire, because all the holes were shut. Pretty amazing stuff if you ask me!

I followed the directions, they were easy to follow and the process was easy too. I removed the valve stem, put in 5 ounces of the solution, then put the valve stem back in, aired up the tire and it was instantly fixed... amazing, especially considering why the tire was flat... I should have taken a pic of the spikes.

I did roll the tire around a bit, then mounted the tire back on the tractor and went right over and mowed my elderly neighbors lawn, so it got plenty of rotation time. That was about 4 hours ago and the tire is still rock hard.

Like I said, I'm ordering more because after seeing this everything we have that runs slow will have this stuff in the tires!

Oh, one other thing. The fix-it flat stuff in a spray can, DO NOT USE IT for applications like this! Because that stuff if left inside will actually glue your tire to the rim. Tires have been ruined trying to pry them away from the rim after putting in fix-a-flat, or whatever that crap is called. Sadly this "TireJect" is not recommended for high speed travel, it will through your tire out of balance. So use the fix-flat stuff in an emergency, carry one in your car just in case. Just make sure once you get the tire fixed wash the tire out real good before remounting it.

I have never written such a long review in my life, but if you got through it I hope it helped. It's not often a product lives up to it's claims today, but this one in my opinion surpasses it, so I felt the need to say something. Besides, the warning about the Russian Olive tree just may save someone a lot of frustrations.

I recently bought a new riding mower and before I even rode it I put the tireject in... I have giant mesquite thorns in my yard.... mo more flats.. product works.. thank you...
