The "small" has quite a power, in general, never requires a higher level than the first - and to this he is really almost noiselessly. (Ect television.) With noise in the living room is however no longer really gets the other stages with .... for the money unbeatable and my comparison is in the bedroom, in the form of a column fan which was twice as expensive and noise like an engine produced :)
Processing a quality image, at first glance at least. A closer look will fall even minor flaws in the eye (gaps ect.) But honestly - that's not a sinfully expensive luxury object. Hide not you have him and he performs his sovereign service - I am satisfied and recommend it further without limitation.
