So good I bought another one
I got one of these back in spring and use it mostly in my camper van, space is limited so the folding design is great. The wire stiffeners inside are a bit fiddly to use but hold the basket in shape well once fitted, so it doesn't collapse when filling it up. Capacity is 21 litres so it holds quite a lot of stuff, and does a fair job of keeping things cool. Quite sturdy with an aluminium frame and handles and low enough (just, with the handles folded) to fit underneath the van, in the shade, on really hot days.
I like it so much I've just bought another one.
