I love this unique fan! I didn’t order it because of the Bluetooth, but it’s an added bonus. Air flow is great. I’d give it a five star except for the fact that the instructions were not very clear.  My husband installed the fan and said it was a nightmare. He’s installed several fans throughout the years and this one was his fourth in our new house. The instructions were in broken English and the diagrams didn’t match the number of screws. After much cussing, he got it in place!
