MSR PocketRocket Ultralight Backpacking, Camping, and Travel Stove, PR 2: Ultra Compact

Where is it made?

How long does a fuel canister last with this stove? Planning a trip would like to know how many canisters it would take for a week....

How adjustable is the heat?

What is the smallest pot diameter this stove will hold? I have a small pot that is only 3.5" in diameter and think it may not be stable. Thanks
