Recently I thought I had lost my Trangia gas converter

and saw these VERY VERY cheap gas converters that looked identical ? but in the description it said propane ? I wasnt sure if the thread was the same as the UK butane tins
so long and short of it I took a chance and gambled and bought one it said up to 30 days from HongKong
BUT !!
it came today 12 days from ordering and guess what its identical
it works exactly the same as the Trangia one that I found the day after ordering this one
but as I have 2 Trangias the series 25 and a series 27 I can keep one in each
NOW
THE GOOD BIT !! the official one a Trangia Gas Burner Retail RRP Price is 55.00

but !!!!!!!!!!!!!!! FIVE TIMES CHEAPER !!! https://www.ebay.co.uk/sch/i.html?_f...c=1&rmvSB=true
