The doubts were entirely unjustified! After 3 weeks, my conclusion.
I did some commercial canola oil in the tank, trying desperately to spray. Nix came out. Read instruction manual :) !! The spraying mechanism works in the pressure to build to the cap. Before each use to make up and down -movements with the cap). At some point you have it in feeling, but if you like include ... 7-10 times are a good guideline.
The undiluted oil is finely atomized.
Finally, in the hot pan a fine film of oil spray (which was previously rather useless with the diluted oil). Multilayer omelettes or even to burn prone potato products (gnocchi), no longer a problem (the right level is also very important). A review referred to the fact that you have to build up enough pressure and that his spray pressure not endured.
Very possible that he has received a defective piece, but if not, should be mentioned that when too much pressure this in my opinion been relatively stable container probably yields. This is not a propane-steel container. The stainless steel sheath of probably not even likely to be the problem, but the seals. If I pump about 10 times, then you could tell a lot of pressure, all you need not at all, so that the oil comes out atomized. But I can well imagine that in 20 or more of the pressure is enormous to me. This holds out no simple rubber seal or plastic.
So do not overdo it with the pressure.
