The bellows of Hama has two advantages. The first is his, already mentioned "Power". The is really good and gives the word "pneumatic" ne new dimension. Moreover, it is inexhaustible in Hama also, in contrast to the compressed air doses.
The more important point is for me but the nozzle. The comfort zone long while "Dust Ex". You can access even lying in the housing places without problems. The nozzle is also rounded, which prevents damage during any contact with mirror etc..
The price I find frankly on the border. But that's with many items in this field like that.
Perhaps only briefly to smell. My bellows no longer smelled so strongly. This may on the one hand be due to some time past production time. Secondly, that's a very subjective perception. A Vorrezensent has described it well. New tires. Since rubber is also glued or vulcanized. The then smells just like that.
Conclusion: the tool is (n / woman) for photography just need point
