Digital Infinite Repeat Cycle Timer Plug with Countdown and 24 Hour Daily on-Off Programs for Electrical Outlets, Lights, Hydroponic Pumps (120V, 15A) [2 Pack]

Timers came with an excellent instruction manual and they are very easy to use. They are working perfectly for my hydroponic tower planters that have a pump in the base. They have a battery backup to keep the time, saving me the hassle if power goes out. So far so good!

It’s working great. Good instructions for setting it up. Not super intuitive but it walks you through the setup clearly.

It does everything as advertised albeit somewhat difficult to follow the included instructions. One limitation is that it can do only two daily on/off, if you want to do more than two, you are limited to one set of on/off times then set interval ons/offs between the one set on/off times. example daily on 6pm off 12am then interval on for 20 minutes off for 2 hours between 9am and 6pm. you get about 3 20 minute on periods between 6pm and 12am, don't think you can dictate the exact time of on/off by doing it this way. I wanted 3 minute on 12 minute off repeated between 9am and 5pm. It took me four tries to get it right, although if I had followed the instructions to the tee, I should have gotten it right the first time, so blame me. the other limitation is this timer does not display the amount of time remaining in the 3 minute on nor the 12 minute off period. So you have to stay with the timer for at least one cycle (15 minutes for me) to confirm that the timer is set correctly. This timer replaced my solar water heater pump controller that would have cost me about $150, so I am saving about $130 and I have a spare timer.

When I received the timers, both had been charged and displayed the time. I did not have to plug it in to program it. The time is displayed in 24 hour format so there's no mistaking AM or PM. The buttons are fairly large, nicely labeled and well spaced so you don't accidentally hit 2 buttons at once. I immediately used one timer to replace a noisy, standard mechanical timer. The instructions are more visual than text with each step clearly illustrated. It was easy to program to the current hour once I realized I had failed to read the "hint" to hold down the "confirm" button until the time displayed blinked, making me feel really stupid. The timer is fairly large. It covers both outlets when plugged in. I easily programed it to turn the light on at 19:00 and off at 22:15. I plugged it into a three plug adapter, plugged the adapter into the wall outlet and the lamp into the timer. It worked perfectly that night. The next day I looked at the second timer I had left in the box. After 2 days of shipping and an additional day sitting in my house, the backup battery appears to have worked for at least 72 hours. That's a lot more than I expected. This timer is described on Amazon as being for indoor use only but there is no information in the instructions. I would not consider using it outdoors unless this was specifically stated.

Indoor timer, easy to set, works well. I've purchased several for various uses. The display is easy to see. I would buy again.

When I go out of town for an extended period of time, I use this timer plug to pre-program my lights to turn on/off as a home security measure. It's timing is highly accurate, & it works reliably every time. However, the setup process is not intuitive at all. Since I don't go on lengthy out of town trips too often, I find that I must refer to the instructions every time when I need to set it up. It's probably time for me to join the information age & just buy a Wi-Fi-enabled smart plug when I find one for a reasonable price. Bottom line - it works, but the design is not particularly convenient.

I have several timed light switches from this company and ordered these timers as the on-off timers were out of stock. These timers are not exactly what I had in mind but have worked out well. I use them to turn off certain electronics (an electric water heater and yogurt maker for example) after specific time. I understand they can be used to turn things on as well and have other more complicated programming. The only issue for me is remembering which buttons to press! So I have to refer to instructions periodically. That said, I would still highly recommend these.

Love these timers. I use them in my aeroponic system for controlling solenoids to effect misting 10” on 9’ off. I have 12 of them. Two have stopped working after three years. The clock time drifts a few minutes per year. Otherwise they have been great. I especially like how easy they are to program and the price is good too.

This will do pretty much whatever you need it to do.

would be better to have 3 functions. 12 hour cycle, 18 hour cycle and manual function

Ce dont j'avais besoin pour un réfrigérateur avec un circuit bloqué en mode continu. L'estimé de réparation se chiffrait au dela de 400$ pour changer un petite carte électronique... Cette minuterie permet des pauses tout au long de la journée et empêche le moteur d'opérer sans arrêt et de surchauffer..

Works fine and easy to use.

Nice looking, appears to be well made. I purchased these timers in order to run a 12 volt motor for 1 minute then to stop it for 29 minute, this cycle to be repeated from 09.30 hr till 16.00 hr. Then to be shut off overnight to restart at 09.30hr. the next day. The cycle repeats each day of the week. Setting the time of day by following the instructions was easy. But I have not been able to make the timer follow my instructions, which were as in item 3 - interval circulation working mode per day.. advice on how to meet my needs will be appreciated.
