+ Processing convinced as the entire protective structure including the rotor blades of metal.
+ Volume is also convenient, any normal fan makes more noise.
- Since it is powered via USB only sometimes is not enough power to get out of the rotor blades in the transition. A small spin around the longitudinal axis, however, is sufficient and he turns his joyous circles.
- Thanks to the low price probably have to be taken or design flaws in purchase small material. For me, a small imbalance has crept which, when the fan au directly the table is to ugly noises or vibrations leading causes.
Both negative points do not bother me in the slightest, I just put an old mouse pad underneath, any comparable object fulfills the same purpose (for example, Notepad).
I can recommend the fan for that price. Those looking for a perfect model should spend a little more.
