i have several "copys/clones" of the Primus type stoves that were made in Korea.they are all of the highest quality with add-ons not found on the Swedish stoves like pre-heater blow torches and fuel gages.i would trust a Korean stove to perform too high standards with no problems at all.
any info you can come up with on Korean stoves made for general camping,canoe tripping,where light weight is not a issue would be a good subject.
