Bought after another product of the same kind but not suitable and I'm very happy. Besides the fact that it is not imposing and so easy to store, it sends a good compressor air jet and cleans many surfaces and number of devices to remove dust and / or dirt a little thicker. The engine is not huge and did not allow a sustained but it is ideal for home use or semi-professional use. I recommend the product because it avoids disburse 200 tickets or more for obtaining a vessel which itself rests solely a pro use.
