The bike is worth gold! Warm in Bude, fan and cooling ZACK. Takes not so much space as a "real" table fan and does its job hervoragend. Quality is fine, of course, the extent of which it is a plastic fan. The only shortcoming is that the switch for the fan speed is quite stiff so that one stop but must hold times with the other hand to switch. But due to the advantages and the power of this small Gimmiks I can overlook that.
