VIVOSUN 7 Day Programmable Digital Timer with Dual Outlet, 20 On/Off UL Listed Heavy Duty Plug-in Outlet Timer with Countdown Setting, Indoor for Lamp, Fan, Heater, Humidifiers, Aquarium (1 Pack)

Purchased 4 of these February of 2023, thus far they worked well for 3 spring growing seasons. Turn on the lights Mon-Fri at 6:30am and turn them off at 8:30pm. Then on Saturday and Sunday turn them on at 8:30am and turn them off at 8:30pm. Easy enough to figure out how to program them and have a lot of functionality that I do not use.

Does what it says on the box. Easy to program. Easy to temporarily switch the schedule to on/off when needed. Would buy again.

This product appears to be a good timer. It did not come with instructions and the one offered onAmazon was for a different timer. I ended up going to Youtube to get instructions. It is not that hard once you know how to do it, but would have saved a lot of time if they would have included instructions for setting it up.

Works great solid

I bought this timer to control the on/off cycles for my drip system. My drippers only drip .5gal per hour and I set the timer to only be on 20min per day- no way it could even drip a half gallon per day if the the timer was working correctly. I come home one day to find my basement is flooded. The mode was set on auto off and I was completely confused as to what had gone wrong. I reset the timer and set the exact same on/off times and put it on auto off again. I watched the system go through an on/off cycle to see if it malfunctioned and it was fine so I assumed I fixed the issue. The timer was working and my drip system was operating how it was supposed until about a week or 2 later I find all the water has been dumped on my floor again- the timer malfunctioned again! I’m not sure what’s wrong with this product but it’s extremely inconsistent and will randomly just stay on instead of shutting off when it’s programmed to. I’m switching back to a mechanical timer- I can’t program it down to the minute but at least my floor won’t flood!

Once I figured out how to set it ( which was very easy and easier than other ones, I love it. Gonna buy another for my nursery tent. It allows you to set timer for your lights or anything that you want on and off at specific times. Good value as well and way better than the push down models.

Programming options are endless. Upon delivery, she had battery life. I didn't realize I could automate everything. Obviously it has all the buttons, bells and whistles, that I'm not used to. It has no bright lights to disturb a flower cycle as well.

The instructions are less than adequate, worst customer service ever.
