Forgets programing often By Nicole on 5/23/2016Nicole wouldn't recommend this product to a friendThe timer came with no instructions, Once I figured out how to use it I got it seemed to work. After a couple days I noticed that it was not turning on at the right time. I reprogrammed it. I thought it was working fine but then a week later I noticed that it was off during the day and turning on at night. There are no directions so I am not sure how to fix it. I liked it since it allowed me to plug in my grounded lights. Hopefully I can figure it out.
Great product By Diane on 5/11/2016Diane would recommend this product to a friendGreat product, I have 4 tanks and now have timers on all of them.
Knock on wood no issues for 8 months.
I great Time with some minor issues By LBK Reefer on 11/30/2015LBK Reefer would recommend this product to a friendOver all this is a great timer and I have ordered another one. Two points to clarify for others is that you cannot control the two outlets separately, so if you wanted the right outlet to go on at 12:00 and the left at 1:00 that is not possible. The other point s that I had the time plugged into a 4-way outlet and the time blocked the other 3 outlets from being used. This was simply solved with a power strip. Overall thought I really like it and most importantly it is easy to program.
Be careful By Ben on 11/15/2015Ben would recommend this product to a friendA few things to point out:
The smallest amount of time you can control is one minute. Some make sure that is enough for what you need.
You can not control both ports individually.
These timers are big, if you need two or more you might need another extension.
They are easy to program - with the instructions
So far so good By Jeremy on 6/16/2015Jeremy would recommend this product to a friendI cant say much due the timers i bought have only been in service a few weeks. Had to read the instructions to get them to function properly. All in all I think they will do the job.
good, but can you say about a timer By guy on 5/4/2015guy would recommend this product to a friendEasy to program, a little bigger then most timers. A special note, when you program for the auto button the timer must be plugged into a power source for the auto on and off times to work! You cant just program them while sitting around like the time date sequence does.
No problems after six months By Marc on 12/16/2014Marc would recommend this product to a friendBeen using two of these for about 6 months for controlling calcium and alkalinity dosing. These units are easy to set up and use, and the one minute increments are just the thing for controlling dosing pumps.
Great timer By Brent on 8/16/2014Brent would recommend this product to a friendWhile at first I was daunted by all the buttons on this timer, I found it very simple to program. I am using this timer for a dosing pump and it works perfectly. It has an internal backup battery that is charged by line voltage, so you should not have to worry about power loss affecting the clock or programs you have set.
Works Great By Tim Gonzales on 8/11/2014Tim Gonzales would recommend this product to a friendI like knowing exactly when the lights are going to come on and when they are going to shut off. These timers do just that. Plus there is a lot of flexibility in the programming. Monday through Friday I have them trip my lights at 4 pm and go off at 10 pm. This is so I can enjoy my tank when I get home from work. Saturday and Sunday are programmed to come on at 1 pm and shut off at 9 pm. This allows me the most time to enjoy my tank on the weekends. I like the flexibility and the reliability of these timers.
Good Timer By Reefer Mike on 2/26/2014Reefer Mike would recommend this product to a friendI got these at my local fish store. I paid $10 more for them there than here. Rats! Anyway, I have had them in use for 3 years now on my 90 gallon reef and they work great. They trip both lights at the same time so I have them plugged into my two 250 watt metal halide pendants so they go on/off at the same time. I like that you can program them up to the exact minute you want them to go off. Easy to use and reliable.
