Review on 🕛 Powerful Timer Relay, DROK Time Delay Relay DC 5V 12V 24V with LCD Display, Micro USB 5V Support – Delay Controller Board Delay-off Cycle Timer 0.01s-9999mins Trigger Delay Switching Relay Module by Jason Porter

I found the DROK timer to be very versatile in its modes of operation and worked for the application I was using it in. However, it has some disadvantages. First, the user manual must be transcribed by a native English speaker. I was able to work through the instructions through trial and error and set up a timer for my application, but it would be much faster and easier if the instructions were written more clearly. The second issue is that the LCD lost some of its functionality about a day after I turned the device on. I can still use it but it's very hard to read now. Because it's so cheap I'll probably just buy another one, but that could mean quality control is an issue with this device. Overall I am satisfied and recommend DROK to keep improving the quality of this device. Update 19 Oct 18: I bought 2 more of these and they have an additional problem that I didn't notice when using the first one. of the three I bought. The problem is that the time base that the timer uses for its timing functions is slow. Accurate measurements of one of the timers show that it is off at -6 seconds out of 900. During the day, this corresponds to a loss of 9.6 minutes per day. So if you depend on higher timer accuracy, you won't like this. So since I use it as a cycle timer I am disappointed with this device as my time demands are so high that losing 10 minutes a day is a problem.
