Excellent fan with a plurality of fittings. Price was higher, but I have much time spared in that I did not have to solder cables. Connect an I had him instead of a ventilator with a non-standard connector, and it was enough just slit the cables for both ventilátoroch and combine them Spink, which are part of paraphernalia. They were able shears and pliers.
Quiet nice package perfect for those who alter the lay public ventilator for the first time and you pay for the accessories that you do not need

good quality construction really quiet and powerful Needless to scribble in a package in the form of adapters and Reduction, overcombined a paper carton with the door to the Velcro with windows on both sides. All very well but this is a structural component and not a gift for my girlfriend. I assume increased price zhtol precisely this circus around the package.
