Build quality and usability are at a high level. For stealth cooking it's perfect; in 9 minutes, chicken soup with noodles (490ml) was hot enough to burn the tongue, even in rainy weather around 10°C. To bring it to a boil, I poured a little less than 1/3 ethanol into the cooker. A more future-proof choice is the Triangia Mini set with an 800ml pot and a 155mm pan if you plan to cook a bit more. The HA version is more durable. Planning stealth camping? You must have this!
