Zefal 3.4 ounce tire sealer w/o bracket

Perfect for my bike to keep in my bag

I purchased this to try instead of having to repair/replace a tube and I got a chance to use it today. Got a flat about 9 miles away from home. It worked fine; until I went to unscrew it, and the removable presta valve core came out, along with a fountain all of the sealant and sprayed all over me, the tire, the bike, etc. I was able to get the core out of this using the pliers I also carry and screw the core back into the valve, but the mess was not fun, and most of it was outside the tire. I pumped up the tire using my pump, and it held up for the ride back, but we will see. I am happy I didn't have to change the tube, but the mess was not a thing I was expecting to have to deal with, lucky I also had some water and towels to clean up with. Not sure if it was me being to tight when I went to install it, or I have an issue with the tube. But be prepared.

Awesome product saved my ride, the inflation foam stoped the leak, gives enough pressure to get back. about 60psia bit messy but so is a walk back to car..

Doesn't work. Total waste! I feel so used! Save your money...!

Quality Zefal product, I may never need it, but if I do it should get me pumped up. Yes, its probably a good idea to have self sealing tubes, or squirt some slime in. But I feel this is a good investment, rather than pushing the bike ! Pricey though.

Good

This saved my bacon on the road today. Worked great! Tire went flat in maybe 15 sec? That's a fast leak. One thing: BE CAREFUL when you screw this on. I cross threaded it at first, so didn't get the full effect.No problem, though. Just broke out the pump for 30 secs and off i went.

Finally had a chance to use this stuff on a ride today.IT DOES NOT WORK!Ruined my day.Don't let it do the same to you.I came home, inflated with Fix-a-flat and rode on.Don't waste you money on this as I did.
