This product I ordered, etc. during the cleaning of my electronic equipment such as laptop, stereo, keyboard. The shipment was quite fast and the product was securely packed. The box is about the size of a spray can as we know them from the painting. The air pressure is good, but you should make sure the can just to keep otherwise the liquid content is blown out with. In addition, a glove would recommend because the can is cold uncomfortable during use after 2-3 minutes. The smell of the air reminded by the butane to a gas burner but that quickly disappeared in a normal room. The associated Rörchen is thanks to the cap of the can is always in the right place and will not be lost. I now cleaned for some electronic devices and had caught me as I was looking for other items which I formally "free blow" can. So I have the compressed air sprayer also taken to blow out the spark trap doors of my car to remove the dirt threatens otherwise falling into it. Unfortunately, the contents emptying faster than expected, which has something to do with the blowing out liquid contents in an inclined position. But unfortunately deliver a star.
Conclusion: strong buy recommendation, such a box in the hindquarters to know is always helpful.
