Question: Does this make any noise?
Document: I was such a big fan of digital timers but over the years realized they have all sorts of problems. So I decided to switch to an analog timer to see if I can get more reliable results. I use these on fishtanks and need them to work properly. So far I have no complaints. They are easy to set and dont make any noise. They drift a little per day and are a bit large for outlets but overall they are great timers.
Works great if mounted vertically as depicted. If you're in a situation where it has to be mounted horizontally, the timer mechanism becomes unreliable and unable to stay on schedule.
Works fine. Dutifully turns on/off my GrowLight.
Timer works great with my grow lights and the digital ballasts, no problems at all...Its cheap, it works, im happyThe only down side is the minimum increment of time is 15 mins, so it is not so good for my water pumps that I only want to run for 5 mins at a time, but titan sells the titan 9 that is a digital timer that has 1 min increments, which i also have one of; that does the trick.
This is one of the best 15 min 24 hrs programmable timer on the market Works perfect and is not as big as some other models irTitan Is Name Brand In The Hydroponic Growing FeildWorks Perfect For Cloning Machines !!!!! !
Now, if this baffles any English-speaking consumer then perhaps the timer is not the problem. Great product and well-done, Titan Controls.
I've had this in constant use with high amperage and it performs it's job with no hitches. No complaints here
I threw away some old timers that were horribly loud. The constant ticking drove me crazy. This Titan timer is extremely easy to use and makes no sound. Better yet, you can have it set to go on and off a bunch of times every day without having to use plastic clips that get lost and are hard to grab.
I have had two of these, the first one was broken right out of the box, with parts rattling inside. The second one seemed to be working fine for a few days before I noticed it wasn't keeping time. By the end of the third or fourth day the timer was close to six hours off. I tested this again by itself and got similar results. For the price this thing is built extremely cheap.
Having looked at many other mechanical timers that cost 5 to 10 times as much, this is a great value, because EVERY fifteen minute interval in a 24-hour day can be set to be on or off.
Answer: yes
