Weve loved the Reactor systemwhich integrates a burner, pot, and heat exchanger for superfast and efficient performancesince it won our 2007 Editors Choice Award. This new 1-liter version is ideal for solo hikers. I used it on a nine-day, 200-mile hike along the Pacific Crest Trail and burned through only half an 8-ounce canister (cooking breakfast and dinner for one). Boil times averaged less than two minutes in temps down to 30 degrees F. The puck-shaped burner nestles securely into the tall aluminum pot. The stove burns ultrahot (theres virtually no simmer) and the pot lacks a nonstick coating, so its best for boiling water or heating up simple meals like ramen.
