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 is a lengthy description of my experience. Scroll down to the last paragraph if you want to jump to my recommendation.I purchased this timer back in 2022 and used it for a short while before unplugging it and putting it away for when I might need it sometime in the future. This year I decided to do some additional Christmas decorating and thought I'd use the timer to control some of the lights. When I plugged it in, there was nothing on the display and none of the buttons worked. I pulled out the instructions and saw that the internal battery needs to be charged occasionally and so per the troubleshooting guide, I plugged it in and left if for a few hours thinking that would be enough to get enough battery charge to allow me to program it. Unfortunately, that did not do the trick. Still no display or function.At that point I decided to open it up to see if I could replace the battery. Unfortunately, the battery is soldered onto the circuit board and so it's not easily replaceable. I've done some electronic work before and so I figured I would remove the battery from the board and see if I could get the company to send me another battery (I would purchase it since the unit was a couple of years old). The website of the circuit board manufacturer (not the company selling the product) is stamped right on the board and so I reached out to them first to see if I could get a battery. They responded right away, telling me that they couldn't send one to me but that if I wanted to, I could use the unit without the battery (something I hadn't tried up to this point). Sure enough, I plugged it in and it worked. However, the display was a little difficult to read due to ghosting of the non-active LCD digits but I certainly could have programmed and used it if I wanted to. The other issue is that without the battery, any power interruption would cause the setup to be erased. So, I ended up not going that route. In addition to all that, I searched high and low for a battery for this unit, but there are no exact replacements to be found -- anywhere! By that I mean, there are batteries out with similar size and electrical specs, but none with attached tabs oriented in a specific way that allow for it to be soldered on to the circuit board. BTW, I was also impressed that the board manufacturer gave me the electrical specs of the battery (1.2v, 40mAh) was engaging with me on how to make some modifications myself to get the unit to function either with a non-rechargeable battery and/or to get the display to eliminate the ghosting when used without a battery.At the same time I was communicating with the board manufacturer I had also reached out to Techbee, the seller, explaining the situation and asking if I could get a battery from them (their email is listed on the back of the timer). They too got back to me in less than a day with a very nice and detailed email, expressing their regrets with my experience using their product and explaining that they could not send a replacement battery. However --- and this is why I gave them 5 stars --- they offered to send me a new timer free of charge without me even asking for one! I get that this is not an expensive item and their cost is going to be less than retail, but being that it was unsolicited I was pleasantly surprised. In addition, they wanted to hear my feedback and experience in using the timer with the battery removed, which I provided them (as I described above), and any other design improvement suggestions simply to make their product better.Maybe I'm a bit jaded by poor experiences elsewhere, but I was truly impressed by their responsiveness, transparency, and genuine interest in making things right.I know that few if any purchasers would go through the steps I did to try to fix a $13 timer (it's more of a hobby thing for me as I like trying to repair broken devices), so if you purchase this timer be sure to follow the instructions and plug it in every month or two to keep the battery charged (it says to do that in the instruction sheet). My mistake was that I didn't realize the NiMH battery, if left to discharge over a long period of time, would eventually become unusable (couldn't be recharged) and that this condition would cause the unit not to function at all even when plugged in.

Purchased this as a way to control the heating pad in my elder kitty's favorite nest. The pad is pet-safe, but runs at full bore whenever my kitty is resting on it, making for a bed that's rather hotter than he likes. I've set up the timer to cycle on 3 out of every 15 minutes at night, and it's keeping my boy comfy now. The combination of the pet-safe pad and timer is ideal for my kitty's needs, and saves considerable energy over other solutions.Programming the timer for combined modes was something of a learning curve, but I found the video that is attached to the product on the Amazon web site to be helpful, esp when it comes to the details of setting up and activation of mode 3. Watching it revealed the "trick" to getting the blinking bell symbol was to start the cycle timer _after_ starting the day timer. There's more, but reading the booklet that comes with first, followed by a careful view of the video, answered all my questions.All in all a very good value for the money that works well for my needs, and something I recommend...

Works as intended. I use this with my smart plug Alexa to turn on at 4 pm and go off every 15 minutes until bedtime for my hotel collection diffuser

Works great for what I need. Pretty easy to set up. The only thing is you can only set up a scheduled time (e.g. turn on 10am, turn off 6pm) to turn on and off, AND a repeat cycle if the repeat cycle is set for minutes/seconds (e.g. on 2 mins, off 58 mins) It does not work for hours/minutes (e.g on 2 mins, off 3 hours). This is not a problem for my set up, but might be something to be aware of.

Works great for specific start and stop times or for a cycle timer where it runs for a specific number of hours. We use it to turn off our daughter’s fan when it’s time to wake for school and back on at her bedtime.

I have a woodstove in the basement. Cold air coming down the chimney prevents a good draft, so I purchased a 500-watt flue collar to preheat the chimney. The collar is thermally controlled but seems to run continuously, so I bought this timer to turn the collar on a couple hours before I light the stove. Saves me a ton on my electric bill.

It works so well. Set it and forget it.

I just ordered my second unit hoping a new one will resolve my issue. I use this to run a continuous on/off cycle for a Wayne pump in my (wet) yard. The instructions I have do not address the internal battery and the need to charge it periodically when it is not in use. I didn't run mine for most of last year (drought conditions) and I did not run it over the winter as there was no need and I live in New England and everything freezes. Anyway - I started running it in early March and all was well. I then noticed, it would run the on/off continuous cycle and for no apparent reason just stop running the cycle. This means a wet or flooded backyard. So I learned there is an internal battery and that the battery is dead and I GUESS i have to a) recharge the battery or b) just buy a new unit. I'm trying both. For $13 I can't complain but I wish the instructions were more explicit on the need to maintain a charge.Update: With two units I am able to charge one while the other one is running the pump. I noticed that no matter what I input for on/off continuous cycle, it would only run the "on" cycle for 15 seconds and stop. A charge fixed it. Probably good to do a charge every two weeks. Just turn the unit off and plug it in. The owners manual makes no mention of this.
