All 3 of my LRP 7200 puffed after 5 weeks of 17.5 sedan. They were great up to that point but thinking about it the day they puffed was VERY hot in the sun, I had no EZ UP and the batteries were kind of cooking in the heat!! I think they puffed due to the direct sunlight that day. It's true they are very popular in Europe and if they were all that bad I don't think they'd be selling any.
