Quality camping stove with adjustable flame intensity, it shows reliability during operation. To replace the gas canister, almost the entire blue part unscrews, and when screwing in, a plastic clip attaches and secures it. Unscrewing requires strength and is difficult. Every time it ignites, in the first few seconds, it may make an unjustified adjustment to the flame, but nothing dangerous. I also have another similar camping stove from Campingas, which only unscrews the bottom part of the base for gas canister replacement, which is much easier than this one. Before purchasing it here, do some research in well-known supermarkets because they are cheaper. -2 stars because it has a plastic body, unlike the other one from the same company, and changing the gas canister is difficult.
