Customers find the fan effectively cools rooms by 4-5 degrees and helps pull more air into them. The installation process is easy, and they appreciate the remote control feature. The noise level receives mixed feedback – while some say it’s very quiet, others note it can be noisy when running at full blast. The fan speed adjustment also gets mixed reviews, with customers mentioning it can only be changed in fan mode and defaults to level 4.
