I have chronic back pain issues & as a result need to use ice paks 3-4 hours/day, and anytime I'm driving more than 30 mins. This ice pak is a great size & retains a cold temperature for a long period of time. Given this, these paks are a godsend BUT the seams always burst within a few months of usage - causing the seams to leak/ooze a greenish brown gel --- all over my clothes and furniture. They are good for short-term usage, but do not withstand the test of time in my household.
As someone who is going to need this type of product for the rest of my life, the cost of replacing them over a long term period would ultimately become prohibitive. It's not worth the hassle to repack/ship or the $8 S&H expense to return the defective ones every time they burst, either. I tried reinforcing the damaged seams with silicone, duct tape, cloth tape & super glue - nothing worked.
I would pay more for a more durable product - and can't understand why they don't have the gel solution contained in another interior freeze pak or reinforce the seal on the seams to prevent bursting/leakage.
