The cooker has been proving its worth for a long time on our travels (9 weeks in Africa). Important: always let it dry well after cleaning, otherwise it will corrode). The piezo has failed from time to time, sometimes on one side, sometimes on the other. This is not really a problem, but it is still a small defect. Otherwise highly recommended.
We used it for 1 week while camping during the autumn holidays. easy to use, stable, easy to clean, not too heavy and yet very sturdy. We would buy it again
