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

Works great. Only had about 2 weeks, so far so good. Set up is not difficult but you do have to pay attention while doing it. Its not intuitive. Bought for a radiator heater that has no thermostadt. Plugged into this timer it now turns off/on at regular intervals cutting way down on electricity consumption & keeping room from over-heating. Which means the timer pays for itself.

WOW! This thing works incredibly well. Very well built, accurate, and really easy to setup. I did have to read the instructions, but they were easy to follow and worked just like they said. It has a built in battery, so it came in with the time on. It recharges automatically, so you do not lose your settings when the power goes out. I have used timed power strips in the past, and regret ever getting those things after using this. If I ever need a programmable electrical outlet, I will 100% use this again. I highly recommend.

Bought it almost a year ago, so far it's still working. I asked Rufus about the rechargeable battery (it gets a quick mention in the instruction sheet). This is what it said: The timer has a built-in rechargeable battery, pecifically a 1.2V NiMH cell. It keeps the time and your programmed settings intact during power outages. The battery is not user-replaceable. It's soldered directly to the circuit board inside. If the battery fails, you'll need to contact Techbee customer support ([email protected]) as it's covered under their warranty. To keep it charged: 1) Plug the timer into an active outlet regularly; 2) If not in regular use, recharge for about 24 hours every 30 days; 3) When properly maintained, the battery can hold a charge for around 90-100 days. That last bit about "keeping it charged" isn't mentioned in the instructions at all. I wonder if that's why some of them fail after a year. The "warranty" is 12 months per the instructions.

This is just an "appliance timer", which allows you to control the power for the device of your choice. If you happen to need such a feature, this timer appears to do a decent job of the task. In my case I got this to control the power for the "modem" my ISP provides for my home (as the previous timer I had for this task was finally dying after years of service). This allows me to schedule a routine "power cycle" (turn off, wait a short time, and turn back on) of my internet modem. Because of the scheduling features of this timer, it was most easiest to setup this timer to cut power for 1 minute the same time every night, and otherwise have the power always on. As my modem does take a minute or three to startup (when first getting power), this essentially means I have a few minutes every night when I don't have any internet. However, this nightly "reboot" of my equipment also means that at other times my internet is much more reliable (as my equipment is restarted every night to keep it running reliably). So by plugging my internet "modem" into this timer (and programming the timer to cut power for one minute each night), I've converted my internet from occasionally "crashing" without warning, into a guaranteed short nighly internet outage but one which also "crashes" much less often than it otherwise would. And the best part of this is that this "appliance timer" automates this routine maintainence, so that I need to do nothing beyond this initial setup (I just routinely have more reliable internet, at the expense of a short nightly internet outage)! NOTE: As another poster mentioned, this timer uses a 24 hour clock (vs the more common in the US 12 hour AM & PM time). While this may be an issue for some people that never learned about 24 hour clocks (in my case I don't use 24 hour clocks very often, but I did learn about them back when I was in school), this is still only an issue when you are initally setting up the timer's clock. However, once this timer is setup, it really works about the same as a timer that uses a more common 12 hour clock. So if you can get over the initial setup of this timer, you really shouldn't notice any difference than what you would get with a timer that uses a more common 12 hour clock.

These are great timers that I am using for my grow lights getting ready for spring planting. First, they are solidly made and strike you that the interface is intuitive and not complicated. That turned out to be the case. I just need on at a time and off at a time to repeat each day. That is program one in the very well put together instructions. The timing only uses a 24 hour clock (military time). That is a good thing so that you cannot possibly mix up AM and PM and as a former military guy, that's how my watch is set anyway. The 2 pack is a great value, the size is compact but the buttons are still easily accessible. Bright white color and a very legible backlit screen. Batteries not required.

Outstanding. These timers do precisely what I need, when I need it. The instructions were well-written and easy to follow...I'm considering buying a couple more for my office.
