So the folks downstairs are OK tenants, although they're a bit on the inconsiderate side when it comes to consumption of electricity.This is well-evidenced by their tendency to leave the downstairs bathroom exhaust fan on for extended periods. The fan's vibrations cause annoying vibration that can be heard in the upstairs kitchen. Despite my repeated requests for a little consideration, we don't get any.I finally decided to install this timer in place of the fan's power switch. Installation was a breeze and the timer functions perfectly. I also like that there's no way to bypass or override the timer, so I'm confident that we've finally resolved the issue.Highly recommended!
