The media could not be loaded. Exceptional stove, extremely reliable, efficient and performs exactly as intended and expected!! Will take it everywhere and anywhere, anytime!! Versatile and capable of cooking and boiling with canister or liquid fuel. See canister demo.

I bought this stove with a very specific need: multi-fuel capability without swapping finicky jets/ports so it's easy to use and maintain, without small parts that can be easily lost. Multi-fuel meaning any liquid fuel you can find in the camping section, at a farm, and/or when the power goes out, in addition to hiking canister fuel (upright and upside down). I've used the stove as-is out of the box, but my intention is to fit the stove in my Trangia 27, eventually.Now that you know why I bought this stove, let me tell you how I used it and what i think about it.I've tried it with MSR canister fuel (upright and upside down) and with Coleman white gas from Walmart. I have not yet tried gasoline, diesel, kerosene, or jet fuel.BTUs like nobody's business! It's a hot stove and quickly brings cold tap water to boil. I didn't try it, but i would think simmer isn't really what it does best.I used a 6 quart All-Clad pot filled about 1/2 full with cold tap water. Boiled the water for a few minutes, turned down the heat, and started adding raw vegetables and meat for soup. 6 quart pot was 3/4 full and boiled steady for about 1.5 hours with lid on and no steam coming out. 6 quarts of water weighs 2 pounds (1 kilogram), so 3/4 full is about 1.5 pounds (0.75 kilogram), plus the weight of the All-Clad pot, and the stove was absolutely solid and worked perfectly both times - once with canister fuel and once with white gas.The burner is loud. If you want a quieter stove, there is an aftermarket accessory that will dampen the sound, but you'll never totally silence it. But, "loud" is subjective. Can you talk and cook? Yes, absolutely. Will you disturb Bambi in the beautiful, tranquil, pristine forest and announce to the whole world that you are cooking on a powerful stove that burns pressurized fuel? Yes, absolutely. Can you buy an aftermarket accessory to make it quietER (but not completely silent)? Yes, absolutely.I'll buy a second one, when I can afford it. It's worth it to me to spend the money on a quality and capable product before somebody decides to save production costs and boost revenue by using inferior materials and/or production methods, or decides to completely stop selling the product altogether (both of which has happened to me numerous times).If you're not sure about spending the money but you still want the performance and capability, buy a cheaper stove that you can find. When you become dissatisfied with that stove, I think you'll have a better appreciation for investing your hard earned money in a quality stove that will serve you well.

It's a solid white gas stove. Great for long trips or cold weather. You don't have to change jets with different fuels, which is one less thing to loose

I've been using this with canister fuel so far and can only say it's a lot less easy to adjust than my other stoves. It's powerful, but loud, and more stove for quickly boiling water than any actual cooking. Probably fine for most folks, I use it as an emergency stove, so it's okay, but I'm a little disappointed.

One of the best emergency stoves in the market, but little bit noisy

The multi-fuel utility offered by this product is truly optimum.

Although this stove have an advantage that you are not required to change any parcels for using another type of fuels, plus you can fine tune the strength of the flame. While under high temperature (Due to I put the stove into a backpack oven) the O Ring melts and block the tubing. So I cannot adjust the strength of the flame and the knob is totally blocked. Maybe need to cover the tubing with aluminum foil to avoid this problem happening in the future time.
