Slime is good, pump is a disaster
Style: 1 gal, Style: 1 gal
The only reason I am giving this a 4 star(not zero) rating is the slime itself. The actual pump on the 1 gallon canister is awful. It makes so much mess, so I do not know whether I pumped the slime into the tubes or it all just spilled out of the base of the pump. The bottles worked great, but this time I needed to use more slime for a bunch of tires. What a slimy mess that was. Very poor pump design. Only after I spilled who knows how much of the slime, I finally washed it and was able to see the problem. The cap at the base of the pump got unscrewed and let all the slime lose. I screwed it back up and this should fix the mess next time I use it. Just a heads if someone encounters the same issue.

Fixes flats and old tires like a charm
Style: 1 gal
This stuff is awesome. If you have tractor tires, ATV tires, bike, tires, hell, any tires that hold air. This stuff is awesome. Awesome. Awesome. It does not work for highway vehicles, i.e. Cars and truck trucks. But anything else it’s great. Dollies, air compressors, wheelbarrows, the stuff is awesome dude.

slime is and has always been amazing for bike tires and other small pneumatic tires
Style: 1 gal
this is a great value, I have been using slime in my tubes of my bikes and a small inflatable pneumatic tires for probably 30 years, and I can say slime has only improved, and it works fantastic, this is a very good way to save money, and it works great on goat heads and several other ways your tires can get punctured, I still always recommend carrying a small air compressor or pump, but for the price point you just cannot beat slime, every bike shop should always carry this.

They need to find a better way to ship it
Style: 1 gal
What was left in the bottle worked great. However, the cap was off of the jug when I opened the package. Ididn't have enough for the other tires.
