This was exactly the product I needed for a project I was working on. Turned it on once and it worked, turned it on the second time and it will turn on but it won’t count down. Useless.

The timer itself does what it is intended to do but be aware this makes a loud ticking sound when cranked.As states, for commercial or AKA non-noise sensitive areas but don’t think about it for home living area use.

I thought this wouldn’t work with 220v but it does—my bad. Just interrupts one leg, which is sufficient, but I wired it in downstream of the existing switch which kills both legs, so I don’t have to worry if I forgot to shut off the breaker before servicing my vacuum pump. Always kill the breaker of course! Seems heavy duty and accuracy is sufficient for my needs.Longevity update—Lasted almost exactly one year. Used 4 days per week in a shop to control my CNC vacuum pump. Not great lifespan.

Works as described, good solid feel and craftsmanship. Using at outside pavilion areas at local public park for lights. Will be buying three more.

cheap plastic body. Mostly flat head screws that fit none of my 5 tools in house. Does not mount anything like any other faceplate you have, and will NOT play nice into a mutli-gang box without a custom faceplate job.
