EcoZoom makes these sturdy stoves with a commercial finish in an effort to make clean cook stoves accessible and affordable in developing countries. The design is highly efficient in delivering the heat generated by your fuel source to the cooking surface. The model we tested could handle a variety of fuel sources as well which made this a great unit to have regardless of your geographic location. Even long fuel such as boards or branches can be used in this unit without the hassle of cutting them down to size thanks to the well thought out configuration of burn chamber and fuel rack. Construction and design both exceeded our expectation making this a stove you can rely on. ecozoomstove.com
