My very heavy over the range microwave broke down. Instead of replacing it with another over the range microwave, we wanted to replace it with a range hood. We did a lot of research as there were lot of options available and finally we settled down to this Cosmo QS75 - 30" 500 CFM range hood. We had hired someone to do the installation, he said the unit was very heavy. The installation came out very good, it looks very professional and sleek. The fan is a bit loud on the fourth setting but does the job very well.Overall, we are very satisfied and happy with the purchase.
