We bought one for a family camping trip and it worked fine, as we were packing it. As soon as we tried to lift it, no, it wasn't light as a feather for grandma to lift. The food was only mildly cool when we got there, and within a couple of hours, there was no coolness left.
I wish I hadn't have wasted my money but then you know what they say, you get what you pay for.
Bottom Line: No, I would not recommend this to a friend
