I’m trying to love it, but the struggle is real. Ordered the medium, the dimensions are way off, even if you use the inside dimensions and it’s heavy, stiff and difficult to fold over, it’s getting easier with use. When filled with cans and ice it’s extremely heavy for me to carry around. Now to it’s real purpose…keeping ice. The ice melted in 12 hours, but the water stayed cold longer. The air mixture instructions are conflicting…it’s needs air to hold the ice, and then remove the air or it will melt the ice. Maybe, I just haven’t found the happy medium. I wanted a cooler to keep my lunch while kayaking; the medium is not suited to kayaking. I ordered the mini and it’s huge too, but may fit into my kayak hatch and keep ice long enough for a day trip.
