The text in this review reflect comparisons of the Crux against other competing products in our 2010 hands-on review. You can see our latest Backpacking Stove review here.
The Optimus Crux is our favorite small canister style backpacking stove for warm weather use. It's tiny, durable, fast, and has a very convenient case that stores the stove under a fuel canister. If you plan to bring a small canister stove to high elevations, opt instead for the more expensive Soto Windmaster OD-1RX ($70). Or for $10 less you can get the larger and heavier MSR Pocket Rocket 2. Of these three options, we favor the Crux because of its folding stem and excellent case design.
