Super practical part, thus making housing dusting a lot more fun and it is no longer Albtraub. Who has tried it before with cotton swabs or even vacuum cleaners, know what I mean. The air coming out with a lot of pressure and if you turn on the brain and / or the instructions on the box reads, you know that you should not keep it at an angle. This is inherently so, there is nunmal gas in liquid form out if you hold the part inclined, this is quite normal. Should shake you look at it not (yes, even standing on the can) before the next one comes here and complains ... Can these cleaners absolutely recommend it, something you may from time to time to good use.
