This is a well built cooker, some Japanese reviews complained about the weight, but to me that's a positive and indicates a sturdy unit and it's by no means too heavy to cart around. It is quite large, which was expected, and it easily accommodates two 28cm pots/fry pans. It has excellent flame control, with the low flame setting being very controllable and perfect for a gentle simmer and it's highest setting being more than enough for a pretty quick boil. All in all, a well engineered product and a pleasure to use vs the cheap butane stoves we're all familiar with.
