Easy to fit and service, literally remove a couple of screws, the fan can be removed from the base for easy installation, the end panels/funnels remove so it's easy to then separately wire up the fan, fit tubing to the end panels, screw down the base, put it all back together, tighten the two screws and job done. I mounted it using tap washers either side of the base plate to reduce vibrations, not sure if that was necessary but seemed a good idea. Replaced a 21 year old fan, clearly fans have progressed, this is much quieter and shifts a lot more air (from my paper over the fan grill test). But then I chose this fan specifically because it has low noise (dB) and high throughout for reasonable electric power cost. Using the higher speed setting, it is only noticeably audible in the bathroom, but then it sits on a loft board, right above the bathroom, and most of the noise comes from the vent. In the bedrooms, if you listen carefully, there is a slight hum, but nothing more. That's good enough for me, no need to try the low speed setting or spend effort on soundproofing. The instructions suggest periodically cleaning the fan and I can see that will be very easy as it will literally just lift out of the base after removing the two screws.
