A bit heavy and bulky compared with many other backpacking stoves, but if you don't mind humping am extra pound or two, it can't be beat. Boils water incredibly fast, very fuel efficient. Everything stores inside the pot, which is nice. Was able to carry one in my pack, and boil enough water to reconstitute meals for my family of 4 in a few minutes. After a week in the bush, still had enough fuel left in the tank for a weekend trip.

Works great. Purchased this to use while camping with my sons Scout Troop. Boils water quickly, easy to clean, light weight. This is a big cup it is tight when trying to fit in a backpack, but it was what I was expecting. All the parts fit easily inside to keep everything together.

A great bit of kit - not just for camping

Purchased as a Christmas present after being very happy with our own Jetboil Sumo. We have used our own to make hot drinks, heat water, cook and to reheat vac sealed meals. Not just for camping - excellent for road/day trips, picnics, moving house or during power outages. Really good members price for this particular purchase and quick delivery. Was worried I didn't leave enough time to get this delivered before Christmas but arrived as ordered and in plenty of time to wrap and get under the tree!

A little too big

This jetboil functions exactly like advertised. It is perfect......if youre cooking for 5. Most of the meals I use this for calls for 12 oz.of water to be boiled. The cup holds a lot more than that so I would like a smaller cup in exchange for the lighter weight. That being said, it worked exactly as expected.

Great for involuntary camping trips

Hot shave in a hasty bivouac? Did your battle buddy pack some ramen or coffee instead of his skivies? Did doc fail the water quality test on the water buffalo? Have I got the solution for you! JetBoil that sh!t! The sumo can hold the burner, stand and a fuel canister inside itself so low space taken up in the ruck. Maybe don’t use it inside your tent though. Turn that Fex into a party, bring a Jetboil.

Group Water Boiler Machine!

Let me start by saying I have been using Jetboil Products since before they hit the retail floor- I had a shop demo PCS in my store before they shipped their first retail units. Since then, I have owned the PCS, 1.5L pot, a Flash, 2 Genesises, a Luna side Burner, a Sumo, and a Minimo. I have also used or owned everything from a Svea 123 to an XGK to catfood stoves. Been there, done that. If what you want is to boil water for 3-4 people quickly and efficiently in a 3 season setting- look no further. I also use it on car camping trips with the french press attachment as the group coffee maker either with a Luna Side Burner on my Genesis or on it's own.

Love the larger capacity!

I've used the Jet Boil Flash for years but needed something with more capacity for a group trip I led to Olympic and Rainier National Parks. The Jetboil Sumo was the perfect solution. We used 5 Sumo stoves for a group of 30. The only critique is after boiling it is almost impossible to remove the canister from the burner and it makes it somewhat difficult to pour. We learned to simply set the canister on the burner without locking it in but that seems like a design flaw. I've never had that issue with my Jetboil Flash. But don't let that stop you from getting this stove for your family or group.

Melted heat shield

I recently purchased 2 Sumo Jet Boils, I tried mine 3 times at home at home to get familiar with the product, it worked just fine. I took it on a fishing trip to heat lunch up on my boat, my wife thought it was a neat idea until the heat shield caught fire and completely melted around the cooker. A small piece of melting plastic landed on the floor of my boat, just a small burn mark.

Never head out of civilization without it.

I have used a jet boil in -30 in the long nights of Alaska and the 120 degrees of Afghanistan. It is an incredibly reliable and durable product. As advertised it boils water quickly and efficiently. I’ve never gone camping or to the field without it. This item is a must have for beginners or experts. If you like coffee their French press attachment is excellent as well. If I have extra time I bring a grinder and aeropress. Either way it is an easy to clean, easy to maintain, durable essential for any kit, recreational or professional.

Very effective simmering

I had already a ZIP jetfoil, which has about a 500ml capacity for boiling. This was fine for using freeze dry foods. However some meals need a bit more cooking time. Returning it to the pot meant very quickly burning it to the bottom because the Zip boils brilliantly but cannot simmer very well.I also realised I needed a bigger pot to cook other foods. Discussed this with Snowys staff who readily understood my dilemma. They suggested the Sumo, which has a brilliant simmer control, which allows me to lower the flame and maintain whilst i continue to cook. (my test to date has been in non wind situations) Obviously need to keep stirring.The larger pot does and its simmer control does allow other forms of cooking, eg with 'oven bag' cooking in a water bath.I use a ... MoreI had already a ZIP jetfoil, which has about a 500ml capacity for boiling.

However this pot can stow normal gas canisters and by carefully packing the pot with other items. Boil times and gas use is very good. Great product
