This is a great little stove. It's a bit heavy for extended backpacking at about 12.5 oz (not including fuel) but for the stability I don't mind. It can easily a support a 2 liter pot (full) and heats the water quite quickly, in my opinion.
I love that you do not have to prime the stove before lighting, I also like that the stove is essentially maintenance-free. I have used it for about 2 years without a problem.
One big minus on the stove is actually it's fuel. It uses non-refilable butane canisters which is not very environmentally friendly. Also the canisters shouldn't be simply thrown out, so disposal tends to be a pain as well. Another fuel minus is that it only uses this one type of fuel, meaning you don't have many options if you run out.
For the fuel reasons alone I am considering a new stove, but I may just be an environmentalist who likes options. :)
Excellent stove, I use this stove and also the Pocket Rocket; both use the same fuel canister. This stove is more stable but heavier then the PR. For cooking this stove is nicer to use. On some trips I carry both, carrying both stoves may seem like overkill but you can both cook and make water in half the time; the additional weight of the two stoves combined is negligible. This stove is easy to adjust and light, it has a windscreen and carrying kit. I shopped around and found mine for $22 on Ebay.
