The Primus Lite+ features some great new ideas. The burner and pot mate inspiringly with a design that's not the same old dimple and groove found on every other integrated canister stove. The burner head itself is recessed and shielded in such a way that the stove's fuel efficiency, which is already good, doesn't noticeably drop in the wind. It also comes with a simple and lightweight hanging system - something other stoves charge you more for as an extra item. However, our testers were unimpressed with the stove's weight (heavy for its low volume pot) and surprised by the tiny old-school control knob.

Cons: Heavy for its volume, frustrating control knob

Our Analysis and Test Results
The Lite+ is pretty darn fuel-efficient for an integrated canister stove, a category known for fuel-efficiency. In our windless test it sipped just 0.2 oz of fuel to bring 0.5 liters of water to boil, just behind the others. In our 2 - 4 mph test, it used the same amount of fuel, significantly less than the competition! We think in part this is due to the way that the burner head and piezo igniter are recessed in the overall burner design.
With a 14.1-ounce trail weight, the Lite+ is on the heavy side for integrated canister stoves. This is especially true considering that it's only available with a 0.75-liter pot, so its weight is not an apples-to-apples comparison with the other integrated stoves we tested, most of which have 1-liter pots. Its small size does mean that it takes up less space in your pack than stoves with 1-liter pots.
The Lite+ is ok at simmering. While we got the flame quite low, it felt like the valve had a bit of "spring" in it, returning to a higher level once we let go of it. This made getting the flame low more time-consuming than it needed to be.
Ease Of Use
The Lite+ has some of the best pot and burner mating of the integrated canister stoves we tested. Instead of the typical dimple and groove design, there's a wire integrated into the burner that firmly grips the pot. We were never worried about picking this stove up when it was running.
The piezoelectric igniter lit the stove on the first try about 50% of the time. It did eventually light every time, though sometimes that took 6 or 7 pushes.
The handle on the pot cozy of the Lite+ flips over the lid and hooks on the other side. Combined with the included cord, it makes hanging this stove really easy. This is the only stove in our review that comes with all the odds and ends necessary to hang it, a nice touch in a big wall or alpine setting.
Our testers were surprised by the tiny and old-fashioned control knob. Wire control knobs have been on the scene for over a decade and are found on every other stove in our review that wasn't made by Primus. Backpackers need to be attentive when using this stove, because once it becomes a volcano of boiling water, it's difficult to turn it down without scorching your fingers.
The Lite+ had uninspiring boil times. It spent 3 minutes and 31 seconds bringing 0.5 liters of water to a rolling boil in windless conditions and 4 minutes and 37 seconds in our 2 - 4 mph wind test. If these numbers seem a lot lower than those of the other stoves in our comparison chart, remember that this pot has a lower capacity, and so we used less water in our test. Other stoves were tested with a full liter of water.
We don't think this stove is a bad value. However, we also don't think it's a great value. Stoves that are lighter or perform better cost less.
The fuel efficiency, pot/burner mating, and simple hanging system of the Primus Lite+ seem like advancements that other stove companies should be watching. Some of its other attributes, like its weight and the tiny control knob, are blasts from the past that we were surprised to see on this stove. It's not a bad stove, but our testers were underwhelmed when they compared it to other integrated stove offerings.
