I replaced an outdated under-cabinet microwave with a sub-par vent fan with the UC-PS38 hood. I have a small single-story home with an open kitchen/living room. The hallway to my bedroom, office and bath constantly smelled of food when cooking. This vent hood has drastically changed that! The fan is very powerful even on lower power modes, and I love the self-clean mode and easy disassembly to clean the fan cover. For higher heat cooking, I find the fan must be turned to high to properly remove the smells. The noise level is much less than the previous microwave fan, and the unit looks so much more appealing and really opens the space. Challenging ductwork aside (fault of the previous owners), I found installation manageable for two people (of small stature and without use of tools like a cabinet jack or other hydraulic lifts.) I learned that not all 6" round ducting is sized equally, and I did struggle to find one would fit snugly inside the plastic connecting ring to the duct hood. I would recommend bringing that piece to the hardware store to ensure you have a good fit. The instructions were thorough but I also watched several installation videos on youtube to make sure I understood the process completely.
