Took over 5 hours to install (3 men, one being an ingeneer)… the fan motor will not spin once the blades are installed… the screws holes are in the wrong location (the ones that you should attatch the blades on needed to be shimmed)… it is now installed but still not working properly… poor quality and major loss of time… very loud when you try to put the fan on as it is still not well adjusted no matter what was tried… now that it’s installed, don’t really know how to deal with this issue… veru disapointed in this product… would not recommend :(
