Note volumetric markings on the side of the pot.
The non-stick coating feels silky smooth and slick to the touch. Nothing stuck to it even when I overcooked some noodles – which could be a real mess on a non-coated pot.

The bowl also protects the pot from any scratches if you store either the stove or a canister in the pot. There's a small rectangle of foam that can be laid on the bottom of the pot if so desired such that the bowl does not rest directly on the non-stick coating.

Central to any stove system is of course the stove itself. The Primus Express stove is a nice, well made stove, but at 98 g/3.5 oz is a bit heavy for its class. Many comparable stoves are about one ounce lighter. Yes, that's "only" an ounce, but remember that if on average one can shave just two ounces off of each piece of gear, one would reduce their pack weight by about ten pounds (assuming that one is a typical backpacker that carries 80 - 100 items in their pack). As Colin Fletcher put it so well: "Take care of the ounces, and the pounds will take care of themselves."
The stove comes in a little roll top type bag with a plastic clip closure. The stove bag is tough and well made, but at 25 g/0.9 oz, it's a bit heavy in my opinion. I'd probably just toss my stove directly in the red plastic bowl or wrap my stove in a bandana and leave the stove bag at home.

I can't comment on the long term reliability of the ignition on a Primus Eta Express stove, but I do note that the spark wire sits directly in the flame at all times.

Now, don't get me wrong. I said up front that I like this stove system, and indeed I do. But this windscreen should never have gotten out of the door of the Primus development lab. It's more gimmick than windscreen. Perhaps one could use some aluminum foil or heat resistant tape and block off the hole, but as is, it just doesn't work in any discernable way.
The entire system is held together by a mesh bag and is quite compact as a set. I think the compactness of the Primus Eta Express integrated stove system compares well with the compactness of other integrated stove systems like the Jetboil Flash or the MSR Windburner.

The Primus Eta Express stove system is a really flexible system. If you want to use a different pot on this system, you just do it. There's no steel attachment that you have to carry as with a Jetboil. There are no little screws you have to emplace as with a Primus Eta Lite. Really, you can use any stove or any pot with this system, swapping things out at will. Indeed, had you a stove that you really liked, you could presumably just buy the pot and use your existing stove, but do note that the Eta Express stove is ideally suited and tuned for the Eta Express pot.

Note the 0.9 L Primus kettle on the Eta Express stove. One can use any pot with the Primus Eta Express stove.
If you brought along everything that comes in the box, you'd have a total weight of 530 grams/18.7 oz, as shown in the first table below.
But I wouldn't bring everything. I'd probably leave the bowl at home unless I were traveling with a partner. I'd also most likely leave the little stove pouch at home, and I'd certainly leave the useless windscreen at home. Leaving those items at home, your weight would be a far more reasonable 397 g/14.0 oz, as shown in the second table.
397 g/14.0 oz compares reasonably well with other integrated canister stove systems.
MSRP for the entire (see full component list, above) Primus Eta Express stove system is $130. This compares favorably with a Windburner (MSRP $140) or a Mini-Mo (MSRP $140), but the Primus Eta Express stove does not have a regulated burner. A regulated burner can give one a distinct advantage in cold weather (see Gas Stoves in Cold Weather – Regulator Valves and Inverted Canisters for further information). The Primus Eta Express stove does not have this cold weather advantage. It's a bit higher priced than say a Jetboil Flash (MSRP $100). I strongly prefer the more flexible (both in terms of cookware and what you can cook) Primus Eta Express stove system, but it remains to be seen whether the system will be economically viable. I notice that REI was carrying the Primus Eta Express stove system last year but that they are not this year. This may be an indicator that the Primus Eta Express stove system may not be selling well, but I speculate.
Analysis and Conclusions
Overall, I really liked the system. Yeah, the windscreen is lousy, but overall, this is a really nice system. I found the wide pot was much easier to cook in than a tall, skinny pot. The simmer control is excellent, and I could do real cooking. The non-stick coating is very good; a spider wouldn't be able to climb up the sides of this pot. The pot is wide and low enough that it can be used as a frying pan. It wouldn't be an ideal frying pan, but it would be a reasonable compromise for backpacking, and would be outstanding compared to a tall, thin pot (like a Jetboil). Eggs, even a single pancake could be cooked herein. I'd prefer the Eta Express pot 10 to 1 over a tall Jetboil style pot for frying fish.
The real advantage of this system to my mind is in its flexibility. One gets a very functional complete kit, but one can easily swap out pots or stoves as desired with no adapters or modifications needed.
The Primus Eta Express Stove System
What's good about it?
- Very flexible #1 – use any pot or pan you like, no adapters, no modifications
- Very flexible #2 – the wide pot allows one to cook a variety of foods, foods more complex than merely boiling water. The wide pot can double as something of a frying pan.
- Highly efficient – fast boils and good fuel economy
- Excellent non-stick coating
- Great pot stability
- Silicone coating on the pot handles
- Silicone band on pot lid
- Packs compactly
- Well protected, durable heat exchanger
- The windscreen is a joke
- The stove could be more compact and is too heavy for its class
- The stove bag could be lighter
- Spark point on piezoelectric ignition sticks up and can get snagged
The Primus Eta Express Stove System: Highly recommended (except for the "windscreen")

Disclosures: The Primus Eta Express Stove System used in this review was provided to me at no charge by Massdrop, a "group buy" site. I have no financial stake in Massdrop, neither do I receive any payments for my reviews from Massdrop (or anyone else for that matter). I have received some free socks as a beta tester as well other stoves for other reviews. In addition, I have made several purchases with my own money from Massdrop just as any other member of the public would do. I do not receive any discounts or special pricing from Massdrop. The fact that Massdrop gave me an all expenses paid trip to Rio de Janeiro in their luxurious corporate jet of course had no influence whatsoever on my review (don't I wish?). I do hope maybe Massdrop will buy me a beer some day, but we'll just have to see about that. In the mean time, rest assured that my stove reviews are independent and as free of bias as I can humanly make them.
If you want to, you can join Massdrop via this link: https://www.massdrop.com/r/ETFBT7. If enough people sign up and actually buy something, I think I get a free T shirt or something. Do as you see fit, but you wouldn't want to see me naked, now would you?
