Good video. I tried mine with my 600 ml Snow Peak cup, and it brings 8 oz water to a boil in about 4 minutes. I tried various wind screen tests, and found that it burns best with no wind screen. Of course this was in my garage. Full/new tablets heat faster than already used ~half tablets.
In a breezy field situation, Some sort of wind screen might be required. I got nearly same heating rate with a full height wind screen -- to the top of the cup, but with an open slot for the cup's handle, where air could flow in to the burning tablet.
That pocket model from REI, here's the image -- comments below.
It is more sturdy. In a breezy situation, an additional aluminum foil wind screen might help. This stove weighs in at over 3 ounces, so is substantially heavier than the wing stove. But then no fuel canister knocks off that excess weight. Nice thing about tablets is that you can carry only the amount you need. With a canister, you also have the extra weight of the full amount of fuel.
