A most excellent canister stove. Perfect for a quick boil.
This morning, I timed it using an old Primus Litech Kettle (aluminum) and a GSI Glacier Cup (stainless steel).
Both had 16 ounces of water even though that is more than the safe amount to boil in the cup since the water level is only about 1/2 inch from the top.
The Primus kettle boiled in 2 minutes 45 seconds and the cup took 4 minutes. For both of them, I did not run the stove full throttle, but just enough to have the bottoms covered with the flames. So since the kettle has a larger footprint, it had a bigger flame.


On a side note, for those who use the GSI cup, the Primus lid fits perfectly as an improvised lid that requires zero effort. If I don't pack my kettle, I use the lid as part of my nested water/cooking solution.

And when my tea is ready, the stove is cool enough to handle and put away.
Verdict: Great stove! Small, light, not too expensive, and boils up very fast, and it can simmer if needed. The down side is the simmer isn't that great as I can't get it very low without putting it out. Maybe if I tighten the valve?
