The instructions are on a folded up piece of paper, easy to miss.

7.75 inches tall (about 19.5 cm)

Pros:
Sprays a fine mist.

10 pumps yields 15 seconds (claimed and I tested and seems to be about right).  15 seconds is longer than you think, I need about 4 seconds of spray to coat a 12 inch pan.

You can use your own oil so you can choose what you like.

Cons:
Not dishwasher safe.  With oil, this makes it hard to clean.

No window to see how much liquid you have left, or how far to fill it to halfway  (you need an air gap because you are pressurizing the air, not the liquid)

The bottom of the cap is not finished well,  there were bits of aluminum that were rough sticking out.  I sanded them off but doing so scratched the aluminum up a bit.
