If you're looking for a small, powerful, lightweight stove, this one is a real gem. For backpackers who need to consider every gram, there are lighter models available. Having said that, this one is still extremely light and will fit into the smallest of rucksack pockets.
I chose this one because of the large burner. It's more efficient at radiating the heat to the edges of the pan, which allows the whole pan to be used rather than just the centre.
The piezo igniter is a real asset, no more messing around with matches in the wind.
I've owned a few gas stoves, and this is the best one so far.
