The Druckluftspray meets my expectations. The pressure is very good. I get so clean two computers in my house. For other purposes is very appropriate. With the extension tube of the pressure is a little thinner. The beam is cold and flammable. One should keep the can upright, but it is short term upside. The cans, which I have received, are different from the picture, but it is 5star code 924 634 on it and it is what has been described: a powerful air spray with 400ml content. I ordered three doses, because of shipping. Clear recommendation!
