Comparing this with a similarly priced 400-watt unit I've had for a few years, it has slightly less capcity (1 cup vs 2), and the smoke produced is a bit thinner per cycle and does not go as far, but the cycles are about 4-6 times more rapid, resulting in a much more even layer of fog but about the same volume per unit of time.

If you lift your finger in the middle, it may or may not continue if you press it again, or you may have to wait for another warm up cycle.

You could be guaranteed a full cycle about every 50 seconds
