Review: Pretty worth it - Great product! I was skeptical at first but when I followed the instructions it worked wonderfully! The durability is actually pretty good, I check the air and it's good after a few days and have to repump my tire because I go through a lot of small potholes and bumps along the way while I ride, value for money is a bit pricey but you get what you paid for, honestly it should be worth half the price, it works wonderfully against any leakage and the application is actually pretty simple you just got to follow the instructions, it is actually very messy so you got to be very careful but easy to clean up though, the size is perfect which should last you for awhile. The pump clogging I keep hearing about, all you have to do is rinse everything out with water because it is waterproof, to get the stuff out the pump just pump it with water and the water will clean everything out You don't need to use soap.
Review: Great if you assemble it correctly - Make sure you attach the plastic tube extension to the pump. Has stopped flats from enormous thorns in my fat tire ebike.

### ⭐⭐⭐⭐⭐ This stuff really works!
*by M***N on July 17, 2026*

I don't know why I've waisted money money on Slime, I could not get the bead to seal on the aluminum wheel that has corroded from the Slime so I thought I'd try FlatOut, 10-15 squirts in all 4 tires and a few trips around the yard and all tires are still inflated 2 days later. I'm super happy!
