Digital Infinite Repeat Cycle Intermittent Timer Plug for Electrical Outlet, 24 Hour Programmable Indoor Timed Power Switch with Countdown Delay On and Off (120V, 15A), 1 pack

This product has helped deliver hot water to our kitchen area water loop. I’m able to plug my hot water circulation pump to this device and run 3 minutes on and 22 minutes off during a twelve hour span. This helps deliver hot water quickly to our kitchen hot water loop keeping my family happy and avoid running our boiler unit constantly. This device is in line with the NTI boiler manufacturer’s instructions when dealing with long loops that can take a long time delivering hot water and waste untold amounts of water. Directions for setting up the timer are detailed but it is a bit of a brain tease to get it right. Device is working fine and is a great price solution than other units out there.

No more mechanical sound. Easy to use

I’m impressed with this little timer, which has more features included than I expected. It has a mode in which you can define a continuous on-off cycle where you can define both on time and off time. I found that useful to keep my old Mac laptop’s battery charged without cooking and ruining the battery. (The Apple charger will ruin the battery if left plugged in all the time.). I knocked off one star because the user instructions were not well written, and the device UI is a bit klunky, however I was able to figure out how to use it after some experimentation. I like that it runs quietly. It has a “built in battery” that maintains the programming and time of day. There was no mention of what the battery is or how to change it, but I did see screws to open the case, but I’ll worry about that if & when it fails.

This programmer is a lifesaver...or in my case, a sleep saver! I recently had surgery and was provided an ice machine to use every "20 minutes on, 20 minutes off, & repeat" but the ice machine had no timer--only a power plug. At first, I tried an existing programmer--the manual one with a wheel where you depress little buttons for 30 minute increments, but it didn't work. After searching high and low for programmable timers, I found this one which let's you program for indefinite time on/off for whatever you plug in to it--& it works perfectly!When it arrived, I was concerned that it was going to be a real pain to program, but the instructions were clear and easy to follow. I set up the programmer in under a minute and had the best night of sleep last night-- thanks to this programmer--since my ice machine "automatically" switched on/off every 20 minutes as I had programmed it to do.I don't normally leave reviews but for this I had to...its too awesome of a gadget not to acknowledge and hopefully help the next person looking for a solution/workaround, whether for to a medical reason or otherwise. Highly recommend. I'm glad I found this--& if you're looking for a programmable timer, I think you'll be highly satisfied with this one as well.

Great product - inexpensive and easy to use.I needed something that would run for 30 seconds and off for 2.5 mins. Took about 5 mins to setup (most of that was me figuring out the product). Unit has built in battery backup so you don't lose your settings after power loss.Tons of options for whatever you need. Very easy to set and much better than a manual device or "smart plug".I have a smart plug that is a pain in the a$$ to use. There is a whole process to just connect it to wifi and it takes me around 5-10 min just to get the device to sync. When we lose power or the device is unplugged, there is a high chance it will need to get joined back to the wifi. Every time I join it back to the wifi, it shows as a new device in the app and I have to set up the schedule again.If your not doing advanced home automation with a smart hub or want to control an outlet with an app, do yourself a favor and get this over a smart plug. Super simple, extremely flexible settings and reliable. I could not do the same 30 seconds on, 2.5 minutes off with my smart plug or a manual timer switch.Only con of the device is the size. Doesn't bother me but it will cover multiple outlets of a power strip if you don't use the last plug.
