I've purchased 3 of these for rooms where I need occupancy AND dimmer features. These work excellent for single pole, single location use (for a few dollars more, there is another version available which can work with multiple switches controlling the same load).One of the switches was installed 5 years ago, and still works flawlessly, very impressive. They are also good looking, and very customizable.No clicking, they turn on silent. They also have an ambient light sensor, which can be enabled/disabled in the programmable setup. The switch can be set to no occupancy mode and not turn on when the room is already bright enough, like during the day when curtains are open. Great energy savings.On the con side, these are expensive, but sometimes quality costs. Buy with confidence.PS: If you don't need BOTH dimmer AND occupancy features, there are other models available with just one of those abilities for about half the price.
