I've been using this type of timer for my two outdoor pond pumps (for waterfalls) for years. They turn the pump on in the morning and off in the evening.

About five years ago, one finally failed and I quickly got a replacement at the local hardware store. Then a few days ago, the other timer failed. Off to the store, but I was told that the company that made them was out of business.

I then went to Home Depot and Lowes, and neither had these timers, just complex digital timers that are a pain to program. Many were not for outdoors.

This was discouraging, then a light went on. I went to Amazon, and sure enough they had them, albeit more expensive than the old ones. However, these are so easy to use and so reliable, I got two so I'd have a spare.

You just turn the wheel to the current time, insert a green pin for the time to start and a red one for shutting off. They come with two sets of pins, but you can get more if you want multiple start-and stop cycles. There is a round pin to turn to start or stop manually.

These are slightly larger than the old ones, but exactly the same design. I recommend them highly for simple programming and reliability. They arrived just a few days after ordering. Good old Amazon!

I received this product today and installed it tonight around 7pm. The unit has a horribly loud clicking noise (like a metronome clicking). It's now 2am and it said the time was 8pm. I'm going to return this one and request another. If the second doesn't work, I'll be sure to update this.

Update 6/5/12
Got the replacement & it works as it should. Makes me wonder what build quality of these things are, but the new machine does not do the "metronome click" as the original did. Again if I have issue w/ this one, I will update to indicate this.

Update 7/8/12
The replacement to the original is still functioning as it should. Time is being kept properly. Just let it be known that if your timer is clicking like a metronome that this is *not* expected behavior. I can't hear it working at all anymore.

I have owned 4 of these. I bought this to run my car block heater and a ceramic heater. 11 amp total. it worked for one winter. then the next it wouldn't work, so I bought another and the same thing happened. took it apart and the white plastic peice that keeps the contacts from touching had melted and deformed making it difficult to spin. this was used under the 15amp rating. I even used a watt meter to monitor the output. the 3rd one, the motor stopped moving the time wheel. only have one working now and it is running a 100w light. I went with a digital GE this year.

Style Name: 1 Outlet, 15Amp Verified Purchase
I purchased this timer when I realized our pool pump was driving our electric bill up due to me being too lazy to remember to turn it off. It ended up running 24/7. We needed something that could be outside all the time as the pump plug is a fair distance from the house. It has been running fine for 3 years now with absolutely no issues.

Setup is pretty basic. Once you plug the timer it it just keeps turning all day. The ring has teeth all along it where you place the pins. Once you set the ring to the correct time you place the pins at the corresponding time you want the attached device to turn on or off. In the upper left corner is a small rotating switch. When the pins you place come around, they catch on the switch and flip it's state. This allows you to flip it on or off whenever you need. For instance when I need to backwash our pool filter I just turn the switch one click and it turns off. When you're done you can just turn it another click and it will continue on it's merry way.

Durability is something to be concerned about when something is out in the weather all day long. As I said, ours has stood up to it for 3 years with no appreciable change. The color hasn't faded as far as I can tell and the plastic has not become brittle. There is no waterproofing on the bottom where the plug goes in but because it's on the bottom you don't get rain flowing to it. The cord is a sturdy thick one that probably has 12 gauge wire in it. For mounting you have a standard slot for a screw head in the back.

The only thing I would say to be aware of is the length of the cord. It is at most a foot long. The shouldn't normally be a problem because you will probably be placing this between and existing cord and plug so it will be mounted right next to the receptacle.

We have been through down pours, heat waves and turning the timer on and off. It has not had a proplem. We change the time often, due to weather and it is working great.

You can't really ask for much more when it comes to an electronic timer. Very simple on/off programming and it withstands the rugged outdoor weather. Don't waste your time looking for other times, this is the one to get. We've had one for that's been working for the past 4 years!

Package arrived quickly from Amazon.com, packed well also. Easy to install / set up. This unit was DOA - the manual on/off function worked well. After setting the time twice, it was noted the timer dial had not rotated at all from the time originally set. Holding the unit up to my ear, I could hear the motor running inside. Returning for refund.
