Primus OmniFuel Stove w/ ErgoPump & Fuel Bottle One Color, One Size

Excellent overall stove.I did not give it 5 stars due to the poorly design/choice of material for the windscreen. The screen come folded and was made of thin aluminium. This probably ok if the alumunium material is flexible enough. The screen broke on the folded seam while i was trying to set it up to test for the first time. You better of making your own windscreen out of Heavy Duty alumunium foil (layered several time). It will be flexible, disposable and lightweight (depend on how many layers you use). Just use the original windscreen as a template. You also need to replace the jet for different type of fuel you use. So plan accordingly. Although I carry them all in a small bag along with the useful maintenance tool (it doesnt weigh much).

This is not my first multi-fuel stove, but definitely the most expensive and most poorly engineered. It is horrifically loud (think jet engine) on any fuel, can't sustain a low flame cleanly (not even on canister gas), heavy, and doesn't fold away efficiently.Turns out it is also unreliable and "supported" by some of the worst customer service (thanks Brunton). After reverting back to my light, simple and compact gas burner for normal expeditions due to the Primus stove's failure at, well, everything, I finally took it on a trip where liquid fuel was needed. Somewhere between the first and second use on white spirits, the leather pump-seal turned into crumbly cardboard and failed, leaving me with a useless paperweight. These seals are available as part of a large and expensive package of replacement parts, most of which are unlikely to ever need replacing. As with my previous problems with Brunton products, their customer service has simply failed to respond to me at all.Rather than spending a small fortune on replacement parts, and especially considering the stories I've heard about these stoves exploding, I'll just get a decent stove from a reliable brand next time. It's a shame that Brunton is ruining a classic name with a poor product and worse service.

The Primus Omnifuel is the result of a great evolution for the old heavy (brass) kerosine Primus stoves I used on expeditions on the Scottish mountains in my youth!I bought this stove in Europe (UK) from Cotswolds in London a couple of years ago.This stove is great to take anywhere, since you often cannot get white gas (Coleman fuel) in many developing countries. This incredible stove can be run on aviation fuel, kerosene, gasoline and even diesel, which you should be able to obtain anywhere on earth where there is at least some civilization! While it can also be run using gas cylinders, in many places these cannot be bought and/or they are relatively expensive in many developing countries.There are three nozzles of different sizes for the different fuels. I usually use kerosene or gasoline to run the stove, but when I tested diesel the flame was far too sooty and I had to clean the entire stove.If you use these longer chain hydrocarbon fuels such as kerosene, it is essential that you add a highly flammable fuel to the priming disk to heat the pipes for several minutes before attempting to burn the high molecular weight fuel. I use gasoline for this purpose, but in the old brass Primus stoves I used to use methylated spirits (denatured alcohol).It saves you time and money when you use the reflective base and the windshield included in the kit. This stove can be used anywhere but in most cases a simple Trangia alcohol stove is adequate. Thus, while the Trangia is unsuitable (inefficient/volume of alcohol used) for use in really cold conditions it can boil 1 liter of water in 11-12 minutes versus 4 minutes using the Primus Omnifuel with gasoline at 37oC at sea level. In addition, the Primus Omnifuel is extremely noisy at full blast, but which can thankfully be reduced using the wonderful second valve, but the Trangia is absolutely silent and requires no priming (instant cooking).I actually have 1 Primus Omnifuel and several Trangia alcohol burnersTrangia alcohol burner ($ 15.00) 4.5* rating from 232 customers Trangia Spirit Burner with Screwcap Trangia Alcohol Burner Kit ($ 21.00) 4.0* rating from 20 customers: Trangia Spirit Stove Kit Trangia Windshield ($ 11.00) 4* rating: Trangia Minitrangia Windshield Trangia 28-T Mini Trangia [N.B. I have also compared the Trangia alcohol stove with other alcohol stoves (e.g. those obtained from Vargo which are too small) as well as Trangia copies (e.g. Highlander) and they simply don't compare to the ultimate model which has been produced in Sweden for over 100 years!]You can also get the Trangia stove with complete sets of pans (25 (larger: multi- person) and 27 (smaller: 1-3 person) series) for far less that the Primus Omnifuel stove!Example of a Trangia 27 system (27.3) ($ 67.00 or 111.00)Trangia 27-3 Ultralight Hard Anodized Stove Kit Trangia 27-3 Ultralight Hard Anodized Stove Kit Trangia 27-3 Ultralight Stove Set Trangia 27-3 Ultralight Stove Set The fuel supply to the Primus Omnifuel can be very cleaverly turned off by simply inverting the bottle (gravity shut-off valve inside) and the fuel bottles can be obtained in different sizes (350ml-1500ml) in red or green, and those supplied by different companies (e.g. MSR and probably Nova) can be used on the Primus Omnifuel)I've found that the Primus Omnifuel is easy to maintain and there are general maintenance kits as well as a specific pump maintenance kit. By contrast, however, the Trangia, alcohol stove does not need any maintenance!Primus Omnifuel Maintenance Kit ($ 35.00 due to a high shipping cost) 4.5* rating from 9 customers: Primus Service and Maintenance Kit for Omnifuel Primus Pump Repair Kit ($ 24.00) 5* rating from 1 reviewer: Primus Fuel Pump Kit Importantly, if you block a nozzle and break the very thin and slightly fragile cleaning wire on the really very expensive multitool ($ 19.00 with $8.00 shipping!), you very thankfully have spare nozzles in the Omnifuel maintenance kit which can still be fitted using the multi-tool! IMPORTANTLY, NEVER LOOSE THE MULTITOOL!Primus Multitool for OmniFuel & MultiFuel VariFuel Stove With jet cleaner.For those of you who really hate the noise of the Omnifuel, you can purchase an attachment which will claims to cut the noise by 50%, can be used with many (but not all) fuels, but is sold at the very high price of $ 70.00!!: QUIETSTOVE® SILENT MUTER DAMPER CAP for PRIMUS OMNIFUEL BACKPACKING CAMPING STOVE Thus, I believe it really in a question of what you want the stove for, and how much you are going to use it! If you are climbing snow-covered mountains then, YES, I think that you would need it, but for general use and lightweight backpacking, it's too heavy and expensive compared with an alcohol stove with a windshield. Both of these stoves are made to last a lifetime through great Swedish engineering!In conclusion, while Primus Omnifuel stove may be considered to be really over-the-top for general use by many people, and they should then opt for the far less expensive, quiet and maintenance-free Trangia alcohol burner, I still have to give both of them 5 star ratings.The author declares that NO CONFLICTS OF INTEREST EXIST in the review of the products described.

Used this as my primary stove on Aconcagua, the tallest mountain outside of Asia. Worked like a charm. Never had any issues with it. I did not treat it particularly nicely. Didn't clean it. Just stuffed it right back in its sack and forgot about it until I got to the next camp.My only qualm with it, is that it seemed like it took longer to heat stuff then other peoples stoves. But they were primarily using canisters and I was using white gas. So I can't be sure if that wasn't why.

great
