I do not own one but have spoke with people who do.
Great cooler but didn't last as long as a regular soft side cooler. For the beach or lake I think they would be great. As an everyday cooler that gets a lot of use I don't know if they would hold up.
I do like the design and have thought many times of getting one because of how light they are and being light light when packing
Hopefully some others will chime in and change my mind.
