Like other reviewers, I've had to fiddle with the knobs to get this stove to simmer rather than boil at top capacity. Hence four stars rather than five.  But once you address that issue-- and it is a small issue indeed, this is the best all-around stove for heavy use. I use it in my work as a field biologist, where there are typically 4 or 5 people boiling water or cooking meals twice a day for 8 days at a time. While it lacks the bells and whistles that some of its (higher-priced) competitors have, such as electronic ignition, I note that this is the stove that keeps on functioning year after year. It's also the stove that works best with an adaptor, allowing you to hook it up to a propane tank instead of the small bottles.  It isn't the prettiest, it isn't the flashiest, and it isn't the lightest stove available, but it is the true workhorse of the group.
