The lights also work great. The fan totally different story. The first one banged against the housing and was insanely loud. Then next one was damaged out of the box so the installers wouldn't even put it in. My 3rd one was installed today.  It is by far the worst one yet. It only works on high. And don't even think about trying to have a conversation while the fan is on, at least for the first few minutes while it is still running. It's garbage, but it matches the rest of our new appliances, so we'll keep trying. 4 months in and we will see where it all ends up. GE, step up and correct this mess.
