A great little stove, pity that Kovea don't substitute the brass/ steel for titanium they could probably reduce the weight by 40% and it would be a world leader but I guess than would increase the £££'s.
For those who have never heard of Kovea (Korean) try 'Googling' for reviews, there's a lot of positive postings. Quality is good, reportedly Kovea manufactures a lot of stoves and components for other mainstream makes.
They only seem to be available on Ebay, bought mine for £35 inc delivery from Hong Kong, took a week.
I added a windshield to mine to help increase the efficiency.
