IntermaticFF6H 6-Hour Spring Loaded Wall Timer SPST No Hold - Enhance Energy Efficiency with Universal Compatibility - Automatic Timer for Effortless Control, Brushed Metal Finish

Worked exactly like it's supposed to. Nice that it shut itself off. You could use it from 1 hour to 6 hours.

Exactly what I was looking for to replace one the lost it's ability to count down.

I've installed many. They do the job.Installed this one as a thermostat timer.

A solid 6-hour timer. I haven't seen any other reviews mention this, but you can manually turn it back to zero to turn it off, which you can't do with all timers.

Good for my commercial projects

I like these manual switches. I turn on my compressor or heater or whatever, with a twist of the dial. I buy different timers, for different items. All of us have turned on a compressor, and forgotten to turn it off again, and have woken up in the middle of the night with it going off again. This stops that

on time and was just what I needed

I got this for my patio in Costa Rica and the people there usually leave the lights on 24/7 since during the day, they don't realize the lights are on. It gets dark around 6 year around in C.R. and with the 6 hour timer, it tells them to get to bed and not stay up all night playing. Overall a great timer and great invention. I have owned many of these over the years and I have found the longer the maximum time interval, the shorter the life of the timer. This is my first 6 hour timer. Let's see how it last compared to a 12 hour timer.
