Wanted my Dyson already disposed - have jokingly decomposes it and a blown engine found. More than bought these favorable experimental engine and installed - now sucks the Dyson like new again. The sound is with this engine a little different from before, but you get used to quickly. Installation is simple, if you have found the tucked-mounted screws at Dyson, the engine fit as the original. In addition, the completely knocked down vacuum cleaner was cleaned on that occasion in a dishwasher, now he looks so ordinary from again.
