Antti 5 I could not source the cup from European Union so I found one for sale at Amazon.jp. The price was very competitive, and it included taxes and customs and shipping fees. The item shipped to Finland in under a week without any hassle at all.I have used an aluminium cup and stove earlier, but it was 2x heavier compared to the Evernew cup and a lightweight gas stove (460g vs 230g).The lid stays in place very firmly. Handles feel solid enough. The cup has markings up to 900ml, total capacity to the brim is 1000ml so 1 liter.ECA522R seems to be the same cup as this ECA548. 548 comes with a paper-like sewn bag instead of a mesh bag, but otherwise it feels the same. Same size, same weight, same thickness (0.3mm), Made in Japan. The only difference as far as I can see is the box and accessories. The ECA548 model is a bargain at this price and I don't see any reason to buy the more expensive model just to get a different box and a mesh bag.
