Hello!
I had such a problem with my cooler for camping. It had been closing, but the cool was leaking. I tried to fix it, but nothing worked. I found a lot of tips on the internet, but after all, I had to buy a new cooler. This time I decided to buy a more expensive one, but with higher quality. When I started looking for it online, I saw that there are so many of them. When I was buying my old one, there weren't so many options to choose from. A friend of mine, who is an experienced traveler, recommended me to check this
review link to help me. The info there helped me to choose the new cooler because there are detailed review and characteristic of the best coolers, and if someone also wants to buy a new one, maybe, that review will also help you.
