This is so handy, takes up hardly any room in changing bag when folded flat. The lid is very secure so you can be confident it will no leak and make a mess. Because of the grooves where the bowl folds, any wet food can get a bit stuck but only takes a bit of extra effort to ensure its completely clean.
I love this bowl but when I put it in the steriliser the plastic ring around the top melted. Other than having to buy a new one and it being a tad expensive I love it. It means we don't have to take so much out for the day.
