Flash Cooking System - Matrix is rated 4.6 out of 5 by 18.
Rated 5 out of 5 by from What a great stove! After having to retire my old Jetboil stove after a dozen years of use, I am very pleased with my new Flash stove. While very similar to the last stove, the design and time to boil improvements are welcome. While my stove doesn't go camping as often as it should, it is in my car and does a great job when I am on the road.

Rated 1 out of 5 by from Manufacturing Defect I bought one of these about a year back. Several friends of mine use this system and I have seen it work flawlessly. However, my stove refuses to "feed" gas from the can to the stove. After trying the stove with several different gas canisters (all of which worked properly with my other stoves), I sent it back to Jetboil to be fixed. Jetboil shipped the stove back to me, however, I am not sure they did anything to it because the problem persists. I would love to recommend this system, but have been turned off by this experience.

Rated 5 out of 5 by from Blazingly Fast & Impressive I received my Flash Cooking System yesterday in the mail and couldn't wait to get out of work to simply boil water! As soon as I could I boiled 2 cups of water at 42F in 1 minute & 42 seconds! That means that I can have fresh, hot coffee in the woods and on the water via the coffee press kit in under 5 minutes!? And Hot Cocoa in the hands of the kids I work with in just 2 minutes! Super cool! Thank you! Best, Kasey

Rated 4 out of 5 by from First time use Purchased for a Boy Scout backpacking trip so I’ve only used it one time. Worked great, quicker than advertised boiling time. All the other scouts were waiting in line for it rather than waiting for their water to boil over a fire. Color changing boil indicator is an awesome feature.

Rated 5 out of 5 by from The Fast Flash Working as a professional climber, time on and off the wall is precious. Seconds can mean the difference between clipping the chains of a route or tagging a summit before the sun goes down. Being given the opportunity to test and use the new Flash system has been fun. The new system is fast, compact, and efficient. The stats boast a 100 second boil time and delivers. I’m a coffee lover –– being able to wake at 4:30 in the morning and easily boil water and get my injection of caffeine makes projecting simple and focused. It fits comfortably into my gear bag from backpacking to big-walling and can ignite stoke on those below zero days. Nothing beats warmth on those frozen desert days. The only critique that I have regards the neoprene sleeve. When I have the burner on as high as possible, I was able to melt the neoprene. It didn’t happen otherwise at an other adjusted level and I wouldn’t let it deter me from using the unit. Just something to be aware of.

Rated 4 out of 5 by from Nice little system to boil water! I saw this at a neighboring campsite and loved the idea. So I searched and found it on line. It does a great job at boiling two cups of water very quickly with IsoPro fuel canisters. I love it for making coffee at the picnic table without having to wake my wife up using our regular camp stove. Unfortunately the click lighter stopped working (others had mentioned this) but it is easy enough to use a lighter.

Rated 5 out of 5 by from Best Stove Ever My trail name is Jetboil. Can you blame me? It sounds like a jet engine when starting, no need of a lighter, just push a button, and it has a thermo flame on the side that lights up orange when it has boiling water which makes it idiot proof, it boils in half the time as a "regular" stove, and I can even hold it in my hand after it is still boiling hot because of the insulation padding that comes with it. All the parts I need all fits within itself, so no looking for the fuel can, pot, oven mit, and it is steady, so no tipping or spilling the water. Yeah, I'm a bit obsessed with my jetboil. And my hiking leader laughs at me because of the way I talk about my jetboil, and how I go on and on about it, he says I sound like a sponsor of Jetboil, which I am not... But it's an awesome stove. It is my 1 luxury NON ultra light item as there are lighter stoves out there, but for me, Jetboil is easy, convenient, and simple! Joke is, if I am ever lost in the woods, if you want to find me, just look for my jetboil. Nothing comes between me and my jetboil. LoL. Not even my husband! whom I love almost as much as my jetboil. Keeps you warm in half the time! See? Jetboil.

Rated 5 out of 5 by from Great Burner for the Road We love our Jetboil. On long drives we make coffee and tea on the tailgate or our truck. We stop at pleasant rest stops and quickly boil water. On warm days it takes less than 2 mins. On the coldest 8-10. Many years of great service.

Can the flash run on standard propane from a 20lb barbecue propane tank?

Asked by: Calen
Hi Calen, Thank you for reaching out. The Jetpower Fuel is an Isobutane / Propane mixture. The Flash should not be run on straight Propane.

I see and appreciate the reviews regarding the boil, but I don't see any regarding the cooking ability of the Flash. How's the adjustability, time on task, uses other than boiling water. I'm not looking to cook a gourmet meal but the occasional meat

Asked by: Bambamv65
Hello, Thank you for reaching out! The Flash is your go to for the ultimate boiling experience with boil times down to 100 seconds out on the trail!! With that said, this product was designed for boiling only. If you are looking for expanded cooking, please check out our MiniMo, MicroMo or Sumo as they come with simmer control and, with a pot support. pair nicely with our 8" Fluxring or 10" Fry pan.

So the Flash no longer includes the pot support in the package? Or did I just buy one that was missing the pot support?

Asked by: CantUseMyName
Hello, Thank you for your inquiry. The Flash system does not include the pot support like the Mo units. It is an accessory that is sold separately.

HI, What is the low temp that this flash burner will be reliable at?

Asked by: anniebear
Hello, Thank you for your interest in the Flash! The key to using any canister stove in the cold is to keep the canister warm before using it , in a coat pocket for example. The pressure in the canister is proportional to temperature and as the canister gets colder, the pressure drops and therefore the heat output from the burner drops. However, by keeping the canister warm before use, it is possible to use the stove with reasonable performance even when the ambient temperature is at and below 0° Fahrenheit. Placing the canister on or in a small piece of foam to keep it insulated from snow will also help. If you are looking for a stove specifically for use in the colder temperatures, please check out our Joule family. With the inverted canister design, it provides liquid fuel feed for the ultimate performance in frigid weather.

Hello so I have the zip cooking system and love it I use it for forestry fire fighting and want to have the color-change heat indicator cozy for my zip but only see it on the flash system will it fit

Asked by: Ragnum
Hello :) Thank you for your inquiry. I am sorry but the heat indicator is exclusive to the 1L tall cup and would not be a good fit for your Zip. However, we do sell the cooking cups separately and this cup would be compatible with your Zip burner.
