Well I wanted to wait several months to check for consistent timing and this unit knocks it out of the park. I installed it out in my chicken coop to cycle the lights on early to get the chickens laying and to shut them back off after daylight and can say after several months this timer has not lost 1 second in accuracy. The only thing that is a negative is it is kinda awkward setting the pins to set times to cycle but thankfully its rarely done after initial set up.

I'm using this mechanical timer to control my pool filter. I am only running it a few hours a day right now and this lets me run it during the lowest demand times when electricity is the cheapest. Programming is easy since you only need to push down the pins for the times you want it active. It will match male or female conduit with the included adapter.

I installed this timer in an electrical line in a garden shed to time a drip irrigation system. Wiring it was super easy with only three pre stripped and labeled wires to connect, and it was easily set to come on and off on a 24 hour cycle. It's professional grade quality, unlike the cheap timers you can buy at Walmart. This is built for permanent installation in household wiring.

I needed a robust and waterproof 120v timer to periodically run auxiliary lights in a greenhouse vegetable growing setup. This fit the bill nicely and gave a professional look to the finished install.

At first the timer didn't seem to be keeping the right time. It was running about half time. I figured out that it was because the white wire wasn't connected very well so I stripped back the plastic casing a little more so it could wrap around the other 2 white wires. It seems to be keeping the right time now. It's so nice to have times at the holidays but I like this because then I don't have to hunt down the timer each year. It's just there.

I really like the concept behind this timer, it's quite creative and allows for a variety of placement options.Being able to wire it in above an exterior junction box make the termination of this easy and the finish install looks really neat and clean.The timer mechanism is working very nicely and the dial is easy to read and simple to program.Now, this may not suit every timer application as it's a very unique and specific design, but I'll absolutely be keeping these in stock and replenish as needed.The timer is keeping time accurately and I've experienced no issues with this either mechanically or electronically.Great timer!

I’m using this 20 amp timer box to control my string lights in my back yard. The junction box cover door closes nicely to keep the weather out and it is easy to set the timer on it. The wires come pre stripped and ready to go which made set up fast and easy. This is very similar to the indoor 24hr timers I’ve used many times before, but setup for hardwiring in for an outdoor electrical box. Worth the price, would recommend!

This is a nice timer - the case is solid, and the cover over the dial snaps tight and has a gasket to seal it. The wires and wiring connections however, need to be encased in some conduit or an electrical enclosure. This is very easy to set, and requires no batteries or fancy programming - simple as pushing a little tab for the on/off time(s). After the flooding I experienced here, I am hesitant to say this is waterproof as they listed it; it certainly is built to be water resistant, but best to be mounted high were it will never be submerged.
