Edit: Still holding proper pressure at 2-months !!! Had a slow leak where my tire went from 44psi to ~18psi over 2-3 days… Dashboard light would let me know every few days that I had a tire problem and I would inflate the tire back up to 44psi… Anyway, I used this product and filled air back to 44 psi and it’s held the pressure for a month already !!!! Be sure to deflate tire to ~15 PSI before adding the product… it only took about 30 seconds to empty the container into my tire with the tire pressure low. Very happy with this product !!!

Effective temporary fix

Style: 18oz, Style: 18oz

The slim brand has always been an genuine effective fix. I have been using slime since I used to ride on bicycles. Well it is not a permanent fix for if you have a hole in your inner tube it is a great fix to hold you over until you are able to get to either the mechanic or to your local store to get a replacement inner tube. Overall, it's worth every penny and you get plenty in the canister that it comes in depending on which slime you are getting whether that's the plastic bottle for your inner tubes for a bicycle or the metal canister as I've shown in my picture for your SUVs trucks or vans. However I don't give this an entire five stars but more of four stars not because of their product but because resorting to using slime rather than fixing the problem is more of my own problem. ⭐⭐⭐⭐ 👍👍

Don't buy doesn't work

Style: 18oz, Style: 18oz

Terrible did nothing. Even tried to let wheel turn 360 degrees yet the solution get in the tire leak proper. Directions on can differ from instructions on here/Amazon. I followed directions on can EXACTLY and still didnt even hold one PSI of air. I'd be better off burning the $10 for warmth rather then waste it this way
