Primus Eta Spider ReviewApril 17, 2015
- Fast average boil: 2:53 for two cups of water
- Highly efficient: boiled 20 two-cup pots on 100g of fuel
- Simmering is exceptional
- Easy to grab strainer lid
- Flexible fuel line
- Extra-long insulated pot handles
- Heavy; included carry bag adds significant bulk
- Magnetized stove mounts on windscreen lost effectiveness
The Primus Eta Spider simmers as well as the Jetboil MiniMo and is equally fuel efficient, but it’s a pound heavier when packed as purchased. You can’t go wrong buying it if weight isn’t a top concern.
The Primus Eta Spider has some minor flaws amidst its very impressive all-around feature set. While useful, the windscreen could be easily replaced in the field with the simple lightweight aluminum screens sold with many other major stove brands. The zippered pouch, which can also insulate your meal after cooking, adds a good deal of packed bulk. Still, the Eta Spider’s flame can stay consistent just above burner height for extended simmering or roar to life when you need hot drinks quickly. The stove is very tough and the raised, rubberized lid-grab remains the most practical across all stove brands.
A 100 gram canister of Primus Power Gas powered the Eta Spider long enough to boil 20 two-cup pots.
The Eta Spider averaged 2:53 to boil two cups of tap water in calm, warm conditions. The last four boils slowed considerably as gas drained, affecting the average over the lifespan of the canister. For the first 10-15 pots, expect to boil two cups in just over two minutes.
The Primus Eta Spider weighs 2 lbs. 1 oz. when packed in its carry bag. This includes the handheld Piezo igniter and the BPA-free plastic bowl that come with the system.
The Primus Eta Spider performs admirably in moderate breezes, averaging 3:38 over five boils of tap water when subjected to consistent, moderate wind.
The Primus Eta Spider is an excellent stove for cooking. Its simmer control allowed me to keep pasta bubbling right at the rim of the pot for well over 10 minutes. Its broad stance enables the use of larger pots and pans, too. This stove is meant to do more than pour boiling water into a bag.
