Review on ⏲️ GE 24-Hour Indoor Plug-in Mechanical Timer: Easy Programing, 1 Polarized Outlet, Daily On/Off Cycle | Perfect for Lamps, Fans, Seasonal Lights! (Model: 15076, Gray/White) by Michael Schafer

I have bought several of these (3 or 4) and they all work great. They are very easy to use and set up. The only thing that confuses me is that one of them is silent, one is mumbling and the rest is kind of loud. I use one in my office with a light that I like to turn on and off because it's a corner room of the house facing the street and it's very noisy. I switched it to another one and eventually it got loud too. Just understand that you will hear them in a quiet room. I wouldn't recommend them for a bedroom or a room where people sleep like in a studio apartment. But in offices or other rooms you won't be sleeping in, they work great!
