Used large rectangle so far. The large are too big for everyday use. They need to look at doing in-between sizes like 4 litres for small family meals. The small ones are too small for everyday small family use as well. They are good quality although I was expecting something a bit more solid but this is silicone and collapsible! 😀 Will be trying them out in caravan bbq early in New Year and will be using them for Christmas as well. I got them to replace rusting old metal bakeware, and I really hope they perform well for the price.
