T319 24-hour Interval Cycle Timer(2 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.

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.

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.

Extremely easy to program and use. I am very happy to have purchased this exact timer, and I wouldn't hesitate to buy another one if I needed more timers. The instructions are clear, the English translation is very good and I had this timer up and running in less than 2 minutes. The accuracy was spot on and it performed all that I needed it to in the way I expected it to. A very good product which I would buy again.

I know sometimes when my internet gets slow to reset my router and modem but sometimes, rarely, after a storm or whatever I need to unplug them to get them to work as planned. I thought why not use a lamp timer to do it but wanted one that wouldn't lose time if the power went out for a short period of time. This timer works perfect for that. Built-in backup battery that recharges itself. I have it set to turn the power off at a certain time and then back on two minutes later. Don't forget, to do that you have to put in the off time first. See a YouTube video on that. This is perfect when I'm out of town and all of a sudden I can't control my garage door or video cameras. What a wonderful find to know you won't ever have to unplug these again. Pardon the messy wires next to my desk but you can see the modem and router on my fiber internet and circled is the timer for one of them.

So far it’s great! Easy to program. Loving it for my aeroponic cloner!

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.

Worked well to maintain temperature in a small refrigerator with a bad thermostat.
