This is a Panasonic bathroom ventilation fan timer. It can be finely set from 10 seconds (for testing) up to 12 hours. The 5, 6, 8 hour marks on the timer appear distorted, but this is due to the transparent case on the surface and is actually the same as in the first photo. I used it very conveniently, but it became unusable after moving because the number of switches didn't match. The lighting and ventilation fan switches are easy to press and have a pilot lamp. A decorative plate is also included, so you can use it as is. Installation was easy enough for me to do myself by looking at the instructions on the back. Thank you. m(_ _)m
