We bought 2 of these for our porch downstairs (new build) and the breaker kept tripping on that circuit, after 3-4 visits by the electrician to troubleshoot the problem they determined the problem was with the fan, took the fan down and the motor had burned out.  We bought them 9 months ago and they were not installed until November 2019, the other one is working fine and gives off good air.  I have contacted Wayfair to se if they will exchange the defective fan despite it being 9 months ago so we shall see.  I gave it 3 stars because of the defective one but the other fan that works great I would give 4.5 stars
