I have used this same model cold pack for about ten years and it finally went bad, So, I looked for a new one just like I had. I have a severe back problem and I use a cold pack at least twice a day to get relief. In reality bought three of them. Two for me and one for my daughter.
Works real well. I had both front tires on my tractor going flat. I installed Tire Ject two weeks ago and no more flats. I have not added air since. One tire was going down so fast that I could not use it.. I highly endorse this product. By the way I had another type of sealant in the tire that was going flat.
