This is a pretty neat camping stove but the claims seem to be a little exaggerated. I wasn't able to boil 3 litres in 3.5 minutes but nevertheless it's acceptable. I wanted to use this to keep a hotpot going but because the hotpot is quite wide it will be quite hard to keep it fuelled. I have a youtube review .. see "Nt3zUlMK8ao" as the youtube with this as the watch?v= parameter. It would be much better if the USB cable to the fan were much longer but I guess I can purchase a USB extender cable.
