I understand that some people found difficulty operating this unit because of the English instructions that were obviously translated from Chinese. It's actually very easy, once you know which mode you're wanting to use. Google "All You Need To Know About Relay Timer Module" and read the first article.My needs were simple. I have LED strips in my car's grille. When the vehicle is on, I want them on (power passes thru module and to the LED strips.) When the car's engine is turned off, the timer starts. When the timer expires, it kills the power to the LED strips. When the engine turns on again, this process is repeated.For this, I used P-4. Car battery (constant power) directly powers the INPUT+ and INPUT- terminals. The OUTPUT + and - goes to the LED strips. SIGNAL+ connects to a 12V+ accessory fuse via a fuse tap that's only powered when the car is on (such as my car's 12V USB port.) SIGNAL- runs to the the car battery as well, to complete the circuit.Unit maintains memory when power is cut. Perfect!

Pros :Unbeatable price for the multiple features/settings it offers. Compact. Clean look. Have used it everyday for months and still works as new. Acrylic case makes easy to rig addig perforations to run additional wires and push buttons onto the housing.Cons: Instructions seem to be translated from Chinese to English, which makes it really hard to understand. It should be reviewed by an american to makes sure is easily understood by english spoken people.

The product came with no manual or instructions of any kind. After requesting programming instructions from the seller, I was emailed some. Then I had to ask for assembly instructions which were then sent. Then It wouldn't work as the instructions stated. I contacted the seller and was told that my settings wouldn't work that I had to change a couple of things. No where in any paperwork received did it say the settings had to be programmed as such. I then asked for a "complete" manual and was told there isn't one. Don'[t buy this product!

I got this timer as a test for some of my electronic projects. The reviews stated it is versatile, so I got one to see, and it is. You can set the timer to count down in several different modes. The modes vary according to how you want the output to turn on/off, reset, and loop. I must admit the timer seemed complicated at first until I got the hang of it. Once I figured out the modes and how to set them, it was pretty easy. One thing to mention is that the two pins on the left side (labeled Sign and GND_T are the trigger pins. They require voltage to be applied to start the timer. The case is also nice. I show the pictures with paper still stuck and paper removed. Removing the paper requires a little bit of work, but it looks so shiny once it's all cleaned up. All the pieces fit as they should. Once completed it looks like it belongs in front of your project for all to see. Overall, it's a nice timer with lots of options. I see working for many applications, maybe even science projects because it also looks nice.
