The Eta Express is a fantastic bit of kit. If your a long distance path walker or a wild camper, and weight and space are a big consideration, this is where it comes into its own. The whole thing, 220g gas canister included, packs down into the main pot, and the dimensions are small enough for it to takke up only marginal space in your pack. I even take it on day walks now, nothing better than fresh coffee on the hill, beats a flask hands down.
The main feature of the Eta is the heat exchanger on the pot, and it works! It does boil water very rapidly, less than 2 minutes for a full pot, and it has fine enough adjustment to simmer as well. The pot is large, easily large enough for a Wayfarer or water for a dehydrated meal and a brew, and the excellent folding handle allows it to be held and poured easily. The stability is good, and can be improved further by adding widely available feet to the gas canister.
Its very easy to assemble, you can be up and cooking in minutes, and it is also very economical. A single gas canister has lasted me on two consecutive two day trips, and was still not quite empty. Like all other pressure canister stoves, it does suffer a little from lack of pressure from near empty cannisters, and can also take longer to boil in very cold conditions, but its worth the wait! I used it in deep snow on Snowdon recently, and ate dehydrated chicken curry whilst everyone else had soggy cheese sarnies, heaven!! Its efficiency is further improved by a good windshield that fits onto the stove prongs. The stove itself comes in a tough bag, and there is a nice cloth to protect the inside of the pot from damage from the windshield and gas canister.
At £60 (I got mine a little cheaper by scouring the internet), its a little more expensive than a stove/pot combination, but in my opinion is definitely worth the extra few quid.
