Altrec

PRIMUS is now expanding the Eta series with a smaller, more compact stove for the solo trip!

For the best fuel economy, turn the throttle approx. ¾ open. Like all other Eta stoves, you can hang the EtaExpress using the PRIMUS suspension kit. Comes with a net stuff sack.

Very nice stove

Rating:****
Used the stove 4 days this past weekend.

- Area: Mt Rogers/Grayson Highland, VA
- Elevation: 4,500 - 5,300 feet
- Conditions: Windy (20-30 mph) to calm
- Temp: 45-60

I was very pleased with the results of the stove and would highly recommend it. My old stove is a Snow Peak Giga that I'm very pleased with, but I wanted something with a quicker boil time. This stove proved to boil water very fast and beat my Snow Peak hands down.

Everybody has different expection, so I thought I would list mine:
- I don't believe they make a stove that will not be effected by wind. Of course the performance of this stove was less during the windy conditions, but I made the adjustments to position behind a object to block the wind (ie. tent, boulder, etc). Making this adjustment minimized the wind effect.
- A lightweight backpacking stove is not going to be very stable, so it's important to pick a flat surface and pay attention to the stove. I thought this stove performed as well as any other in it's category.
- I didn't expect to get sub 3 minute boil times and 14 liters per canister. Outdoor conditions are always going to effect performance regardless of the stove. I was pleased that the stove out performed others in it's class and I would highly recommend.

As a side note, I had a friend do a similar test with the same stove this weekend and he was also very pleased.

Impressive

Rating:*****

compared this with the jetboil, and went with the primus because I liked the fry-pan lid, and for the included windscreen. Boiled 1 cup of cold water in the morning (reached 36 at night) in a few seconds. I lit the stove on low, put the pot with water on it and turned it to high, and instantly saw little bubbles forming on the bottom of the pot! was at a raging boil 15 or 20 seconds later. I had cooked chili the night before, tried cooking the chilie in the can it came in at first, not wanting to use the included pot which I would have to clean later. It was difficult trying to warm the chili in the can without burning it, so I gave in after remember the pot was non-stick, and poured the chili in and finished warming it that way-- worked great and sped up the process unbelievably. Easy to clean, the titanium non-stick is better than my non-stick fry pan at home!
The stove is great on its own. fully adjustable flame, on high its kind of intimidating. The true genius is the complete system, the coiled metal heat dispersment system on the pot bottom combined with the burner is the best system there is.

Some Good Competition

Rating:****

I thought I had finished searching the market for lightweight stoves after I tried the jetboil, but Primus has stood up to the challenge and created an ultra lightweight stove system. I finally got sick of eating dehydrated meals- so I brought the Primus along on my three day trip into the Wind River Range of Wyoming and found that it worked brilliantly. I can go light and eat my pancakes too! The lid doubles as a frying pan. Both the lid and pot are coated with a triple layer non-stick surface that works great and cleans easily. The Primus ETA Express Stove burns at 80% efficiency as opposed to the usual 40-50% which allows me to save weight on fuel which is important when my pack is already full of climbing gear. The other benefit of this stove is that you can put any pot on it- not just the small one that comes with it.
While the ETA Express is a bit lighter than the jetboil, it does not pack as small. Also it does not hang without purchasing a separate hanging kit. It is always nice to be able to keep the stove off the fuel off the snow on those cold nights.

Pretty Darn good

Rating:****
Used this on a 4 day 3 night AT section hike in PA. I'm happy with the stove it worked well for the trip. Boiled water and cooked meals in the included pot. One of my buddies on the hike had a Jetboil which worked great but I prefer this stove since you can use other pots and pans on it.
One note of caution, when I first got it I set it up and lit it to see what it could do. Well I opened up the valve a little too much and nearly took out my eyebrows, a nice two foot flame coming off it. That being said the heat regulates fairly well with a steady hand.
I highly recommend heat exchanger style cookware as it is extremely efficient and keeps the heat away from the sides of the pot/pan

Instant Hot Water

Rating:****
The first time I fired up my ETA Primus was at Cran Flat campground in Yosemite, the ambiance air temperature was 42F, lightly wind. I was very pleased with the compact, ultra light Primus and easy to operate with a touch of Piezo igniter. At 7000 feet, it took 1 minute 45 seconds to boils a full pot of water, I can also simmer to cook my gourmet meals without using the windscreen
However without the foot support, if you cook with a large pot or pan, it is easily tipping over. The gas canisterand the windscreen fit nicely inside the pot and the entire units fit tighly inside the mesh pouch.
This Primus stove is indispensable for a short hike or an overnight backpacking trip.

Nice stove boils fast

Rating:****
I bought this stove when it first came out about 6 months or so ago.
I happened to see it reviewed in backpacker magazine and thought wow its faster than the MSR Reactor! So I had to try it.
I used it in Yosemite in March when it was still in the 30's
Im going to guess it boiled water around 3-4 minutes or so not timed. I had it about medium high so it was pretty decent for hot chocolate.
Reading others reviews its not the best stove ever, wind will affect it so its best to position the stove so it gets the least wind.
Over all its a nice fast stove and its above my MSR pocket rocket and Supafly.

Perfect stove for 2 to 3 people!

Rating:*****

This stove is great... just used it on a several day backpacking trip at 12k feet and above and it worked flawlessly!! Temps were lower upper teens to upper 20's and still no problem. Also, very fuel effecient. My buddy had a jetboil and had to use his second canister and he hardly had any control over the flame... my primus could turn way down to a simmer or all the way up to boil water in minutes! Very packable as well! I know some people thought it was loud... but that's only if you turn it on full blast and noise really isn't an issue for as little time as you need to run it.

Mighty fine backpacking stove

Rating:*****
Stove and accompanying cookware it pretty top notch. The windscreen worked well in breezy conditions in the catskills and along the hudson, the stove was stable enough as long as you didn't go trying to scrap the bottom of the pot while it was on the stove.

Boiled water quickly, I could actually simmer food on it. I didn't get to try the frying pan yet though.

My only complaint is the stuff sack for the stove is way too small. Getting the pot and stove into and out of the sack is very frustrating.

Excellent stove!

Rating:*****
I really couldn't be happier with this stove. It all packs up neatly into the pot, with the frying pan as the lid. Inside you can fit the pot holder, wind screen, burner, and a small fuel canister. It's lightweight for what it is and packs nicely.

I've used it on a couple of trips so far and it has impressed each time. Lighted up right away for me every time. Boils water way faster than I expected.

No complaints at all. I'd buy it again in a heartbeat.

Great Stove

Rating:****
My wife and I just used this stove on a 7-day backpack out of Florence Lake: fantastic! It boils water exceptionally fast, and is lightweight and very compact. I kept one medium fuel cannister inside the stove, along with the burner, and I used the Brunton cannister foot to add stability when necessary.

I don't know if it was just my particular stove, but I found taking the burner off the cannister was necessary: otherwise, even with the valve shut tightly, the gas escaped.

Disapointing

Rating:***
After all of the hype over this stove, I'm pretty disappointed. But I'll start with what I liked about it:It does have a feel of quality to it, as opposed to the more mass-production feel of the Jetboil. Here’s the pros:- Lever action piezo ignitor, that makes it easy to start without tipping it over, like the push-button variety.- Valve opens up more than the Jetboil, giving you more control over the setting.- The valve portion seems sturdily built overall. Moreso than the Jetboil.- Titanium coating.- Better sizing than the Jetboil. Same volume, but not so tall and deep. It will hold a 220g fuel canister.- It has a handle, instead of a neoprene cozy.- It has a real lid (not plastic), that doubles as a frying pan.All sounds pretty good, but now for the test:I didn’t carefully record the test conditions, because I was mainly comparing the difference boiling with and without wind. But here’s some approximates. The same conditions existed in both instances, except for the wind.Air temp: ~75 degAltitude: 4974 ft.Water temp: just cold tap water. Constant throughout test.Wind velocity: 8-10 mphWater volume: 1 LiterValve setting: one ¼ turnTime to boil with no wind: 6 min.Time to boil with wind: Don’t know. After 25 min I gave up.I tried to boil again, without wind, with the valve on full-blast, after about six minutes I gave up. Even on the low valve setting, the 100 g fuel canister was almost empty after about 37 minutes of burn time.Conclusion: The windscreen is nearly useless. This is partly to due to the burner being placed so far below the pot.I don’t know what REI’s test conditions were. You might be able to boil 14 liters at low setting, but not at 2:30 per liter. It’s either speed or efficiency, but not both. Other problems:- Not very stable. Shaky, even in a low wind. - It doesn’t work with any of Primus’ larger heat-exchanger pots. The pot support is too small. So if you need to boil larger volumes of water, you’ll need to buy a separate stove. The Jetboil is much more versatile.- The carrying bag is too small, making it hard to get the unit in and out. The Jetboil idea is better. You can fit pretty much everything neatly inside the unit, plus you have a cup. I’m going back to the Jetboil. Not perfect, but it’s the best thing out there so far for my needs. [@]
