The moral of the story, for me, is to never buy these tubes again.
D. Brown
I pumped it up, but the slime didn't seal the leak and the tube deflated, spewing the slime all over the tire and making a mess of a fix.

Then, after only three days use (about 28 miles) I got a puncture through one tube that didn't heal!

I used these tubes for most of one season of mountain biking. The biggest threat to tires I have is thorns. The tubes seem to work for small punctures but a large thorn would do them in. They did save me changing tubes on two or three rides during the season. I went through 4 slimed tubes and 6 regular tubes during the season. I ran the slimed tubes about two thirds of the time. I ride about once a week. I would suggest buying some non-slimed extra thick tubes and carry a couple spares. Trick: When a slimed tube is punctured put about 10 pounds of pressure in the tube and turn the tube so the puncture is at the point closest to the ground in a few minutes the puncture is sealed and the tube can be pumped back up. If the puncture is too big the seal will blow out.

I've been dumb enough to try these 4 times and every time the result has been he same. With a normal flat tire you have to stop your ride and replace a tire. With a flat slime tire you have to stop you ride, replace a tire and clean sticky green ooze of your bike, your clothes and your hands. The tires I've used have been the 700 x 19-25 road tires. These require high pressure to prevent pinch flats but at 100+ psi the air pressure forces the slime out with an impressive velocity and there is no time for it to congeal and plug the opening. It just sprays everywhere and makes a mess. It is also very difficult to remove once it dries. Maybe it would be useful on a low pressure mountain bike tire but they are worthless on a road bike.

Last week, I went on my longest ride of the year. I bonked with 20 miles to go on a hot day. Then to add to my suffering, with 10 miles to go my rear tire started to go flat quickly. (More than a thorn hole.) I bought a set of these smart tubes a year ago, and this was my first flat!

Well, I pulled over and pumped up the tire. And I was able to ride another 3 miles with my 200lb weight loading the rear tire before the tire started getting too low on air pressure. I pumped it up again and was riding 2 minutes later, and it held the air well for me to cover the next 3 miles. One last fill of air, and I rode home no problem.

Amazingly, a week later, the tire is still holding lots of air pressure from the last time I filled in on that trip!

Do I still carry a patch kit and a spare (regular) tube? Absolutely! But this tire was worth its wait in gold in allowing to just get myself home when I was physically spent without having to hassle with repairing the tire in the heat.

I have probably close to 2500 miles on my bike. I am an avid cyclist and have done a 100-mile century ride with NO flats whatsoever using this tube.

My daily commute is ~3 miles each way and bike regularly on roads and bike paths.

To be honest I can't remember the last time I've had a flat using this tube. It's October now and I've biked to work pretty much every day since March without getting a flat.

Holds pressure well, no instant flats like you can get with other non-slime tubes. The couple times I've gotten a flat these tubes have done their job to get me either all the way home or to a safe place.

One caveat with these tubes is you shouldn't put air in your tire with the valve at the bottom of your wheel like you were trained. Because of the slime it can come out and clog your valve, so it's HIGHLY recommended you fill up your tire with air with the valve on EITHER SIDE, just not the bottom. It works flawlessly.

I ride trails and bikeways in the Phoenix area. It's pretty much impossible to ride any significant distance in this environment without running over a goat head thorn or some other sharp spine dropped by the native plants.

These tubes perform as advertised, plugging pinhole leaks caused by these thorn punctures. Note however, that due to the sheer number of thorns in my areas, I have also found it necessary to use tire liners (in addition to the Slime tubes) to minimize the number of punctures that the slime has to seal. The reasoning for this: the tire liners by themselves do not stop all punctures, and the practice of using the slime by itself results in quickly depleted tubes due to the sheer number of holes (I've had over 20 punctures in one tire at the same time, the Slime sealed them all without flatting; however, there's only so much Slime inside the tube and it depletes quickly with that many holes to patch).

The combination of the slime tubes and the tire liners has virtually eliminated the flats that I experience on the trails. Occasionally, a tire will go flat overnight after riding; however, pumping the tire and spinning it will allow the Slime to seal the puncture.

Note: I use the 26" Lite tubes on my 29" Mountain bike with no problems. Slime does not offer a light weight 29er tube as of yet, so I use the 26" tube to offset some of the additional weight added by the slime and the liners. Installation of the tubes is slightly more difficult but no big deal. Other than that, the 26" tubes have held up just as well as the "right sized" tubes.

I have been using these for going on ten years now and they have saved me from fixing dozens of flat tires out in the field. Before using the slime tubes, I could count on getting a flat tire about every 100 miles of riding, and I'd have to stop and fix or replace the tube. Liners and other solutions didn't make much difference. With the slime tubes, I might lose a little air and have to pump up the tire, but I haven't once had to remove a tube while riding. It saves a lot of time and aggravation. I have noticed the slime tubes tend to last about 5 years, then the sealant dries up and is no longer effective.
