It took exactly 10 minutes to boil 0,8L of water in -4C in Optimus Terra pot with heat exchanger. Had the silencer on and used Jetboil Jetpower 4 season gas and wind shield. Burned clean and silently.
I bought an old msr plastic pump when this broke down. Despite some reviews, the pump seal works well, preheating without muffler works well in 10-degree frost according to the instructions, the included protective bag is useless, fits in a liter kettle (without a bottle), brewing has not been tried in winter frosts.
I do not recommend!!! Very poor quality, the first time you use it, the gas leaks under the burner. Primus would rather never again.
Has this been in use for about five years now? It works well as long as it is serviced from time to time - it is important to clean the nozzle hole and grease the pump "bag" about once a year. I burn Neste's refined small-engine gasoline ("Neste Pro 4T small-engine gasoline").
Use requires learning. Loud Loud as anything, but does its job and is a reliable game.
What's up, works great. Except at the beginning when the fuel types got mixed up. At that time, a nice German guy, whose wife swore by the gas cooker and laughed a little at the antics of the men working at the table, helped with the maintenance somewhere in the cabin of Karhunkierros. After all, these are a bit of a hobby, but it applies to all multi-fuel stoves. Häkkyrä is naturally a shape that doesn't fit well, and folding it into its good bag with extra tins also requires a bit of practice.
Primus, as always, pleases with quality. And with a muffler nozzle, the burner is also quite quiet.
High quality burner. The cleaning tool, on the other hand, leaves a rather inferior impression. Let's see how long that lasts.
Easy to use kettle
I haven't found anything better on the market! -)
Really high quality made. Neat to use. Thanks to the articulated tubing it can be drained of fuel at residual pressure. Power control Plus if you like to cook.
Powerful kettle. An almost mandatory purchase of a muffler.
The nozzle broke as soon as I opened it, but the warranty service worked great.
Powerful and simple petrol cooker. Pretty easy to service when the nozzle clogs.
Noisy but light and functional
A functional and very efficient kettle based on a single hiking trip. It is also light and goes into a small space. Holds a really loud sound, so the available muffler could be good. Only the cooker control switch looks awkward, and is already warped when the gas is opened.
Good and light burner. Herself only been involved in winter trips.
A working gadget.
Good cooker, size unnecessarily big for single overnight trips.
