24 Hour Plug-in Mechanical Timer Grounded for Aquarium, Grow Light, Hydroponics, Indoor Lighting, Home Appliances, ETL Listed 125VAC, 60 Hz, 1875W, 15A, 1/2HP (1 Pack)

I purchased these timers to control my aquarium air pumps on 15-minute on/off cycles, and they’ve been working exactly as intended. Setup is straightforward. The mechanical dial is easy to read, the segments click firmly into place, and setting multiple short cycles throughout the day is simple once everything is aligned. The timers switch cleanly between on and off without hesitation. Build quality feels solid and appropriate for continuous indoor use. The grounded outlet fits snugly, and the override switch is convenient when manual control is needed without changing the programmed schedule. The two-pack was a great value and happened to be exactly the number I needed for my setup. These do precisely what they’re built for and are well suited for aquariums, grow lights, or other equipment that benefits from consistent timed cycles. Overall, dependable mechanical timers that are easy to use and perform reliably.

It works great and setting the time on it is super easy and satisfying. It does make a soft ticking sound. I don’t mind it but I thought I had a mouse in my room before I figured out where the sound was coming from lol.

This was easy to use and I love that instructions are right on the timers. It’s so convenient, and better than getting out a pamphlet every time! I was able to easily set it to turn my Christmas lights on every evening til ten, and then again between six and seven am. Effortless.

Should have come with clear directions and all but good quality and they work and easy to use

Works well easy set up

Fantastic analog timer. Simple to setup. Works as expected. As the title says, no complaints.

Here are the "good" and "bad" on this product. . . ADVANTAGES . 1. This is the highest consumer rated timer among 179 Amazon.com users with a score of 4.8 of 5.0 stars. Competing brands do not come close. . 2. It will operate with the highest energy demanding devices. The timer is able handle equipment that requires a maximum of 15 Amps, 0.5 HP, or 1,725 watts. . 3. UL tested and approved. . 4. There is a maximum of 96 15-minute settings. . 5. The construction is heavy - very rugged. It is not the familiar light cheap plastic types that are commonly sold in hardware stores. . 6. At $10, the consumer is getting great value for an over engineered and durable product that will last for years. For the quality, it should cost $20 to $30. . 7. It is simple to use. First, slide the side switch to TIMER. Second, use a tooth pick to press down the tabs on the clock dial to set the time(s) for the device to go ON. Each tab represents 15 minutes of activation. Third, rotate the round clock dial and position the black triangle to the present time. . 8. There is no comparison between this product and the competition. Through the years, I have used Intermec and GE brands. These were the only choices on the shelves of Lowes and Home Depot. They were cheaply made; they tend to overheat; and the life expectancy was short. The biggest problem was the limited number of settings. Two or four plastic pegs were provided to turn devices ON and OFF. In other words, the user can only activate the device once or twice in a 24-hour day. These plastic pegs tend to fall off and get lost - rendering the timer useless. . The CENTURY 24 product does not have the above problems. Most important, there are no plastic pegs to insert and lose. Just depress any of the 96 15-minute settings with a toothpick to set a various number of activation times. . 9. The device is grounded for safety. . . DISADVANTAGES . 1. The timer is heavy and big - leaves little room for another electrical device to plug into the electrical outlet. . 2. The manufacturer, Century Products, is not well known as Intermec or GE, competing companies that also make timers. . 3. The timer can only control one electrical device. . . ================================================================================================== . . UPDATE 1: I was too premature with my praise for this product. Of the two purchased, one went dead after two days. . . ================================================================================================== . . UPDATE 2: The malfunction happened on a Saturday. Three hours after requesting that the defective timer be returned for a refund, the vendor contacted me by email. He politely asked for a description of the problem, which I replied. Within an hour, a second email expressed his personal apologies and indicated that a free replacement will be shipped on Monday. . The unit arrived a few days later. It was rigorously tested. The product turned my bedroom lamp ON and OFF every 15 minutes for 16 hours everyday. It was OFF for eight hours, because I did not want the lights flashing ON and OFF while sleeping. The testing will continue for the next few days. So far, the replacement timer is working without any problems. . The reality is that defects in manufacturing happen all the time. This is normal. . What is not normal is this vendor's reaction. It is unbelievable that a company immediately responded to a customer complaint within three hours on a weekend, confirm the issue within an hour, and ship a free replace on the next business day. Such an experience is "an all-time first." I am totally flabbergasted. . Customer service like this puts all other businesses to shame. In fact, it must be emulated by all companies. . . ================================================================================================== . . UPDATE 3: I was so impressed with the product's quality, versatility, durability, reliability, and usefulness that I purchased four units. In operation for 24/7, they were continuously ON since October 16, 2016. During this time period, there were no breakdowns or time inaccuracies. My lights and lamps were turned ON and OFF without failure.

I got two of these timers and was using them on a grow project. They were easier to set up than a lot of other ones that I had seen. was very accurate as long as it worked but one of them just quit working after a few months. Could have been a fluke the other one was still working but this project was too important to me I quit using them. I bought two digital ones on Amazon and never had an issue with those. So while these look nice for the price and I know others that use similar ones without issue, this is one aera I decided not to go cheap in any more. Now on the other hand if you want one to use to cut lights on and off at different times while your gone to make it look like someone is home, I would still get one of these because its not the life or death of my plants. On the rating it is definitely easy to use, when it’s working the timer function and accuracy is spot on. I did not try to get it replaced just switched to a better one.

Excelente producto evita que esté conectado y desconectando las clavijas del árbol de navidad . 10-10

Works great. Easy to set up

Used mine outside in minus 30 degree weather and it worked and didn't freeze up.

Muy buen producto

For an inexpensive timer, the quality of these seems to be pretty good. They're fairly easy to set up and program, however you have to be okay with some variation. In the time, as you can't get it exactly precise down to the minute, but more plus or minus five to ten minutes. They don't really make any noise and since they plug into an outlet, there's not really any need for batteries, which is nice. We got them for our reptile lights, and they do a great job cycling between day and night light cycles. Just keep in mind that if the power goes out and they stop running, you'll probably want to reset the times that are set up as they're mechanical and not digital.
