Solidly built module
This is a solidly built module, well constructed, great soldering and very nicely finished. I feel it inspiring enough to buy another when I need as, although I could make my own, it wouldn't be as good and would be for no real financial saving either. It's being used as a mute function within balanced line studio desk audio outs. Thank you.

Does what it says and good value
Easy to control and does exactly what I wanted it to do - control a 12v pump and double water/Solenoid Valve for an irrigation system

Well made and works perfectly
Compact, easy to use, well laid out and fair value for money.

Reliable, but the relays are poor quality - switch them out for Omron
Like others the board is very good, but the relays have a tendancy to latch in a closed state if they have been energised for a period of time. I switched out the relays for OMRON G5LA-14-5VDC - you can't buy them here anymore as OMRON have discontinued them, but ebay has plenty of listings still from China (i used the seller smallpartsbigdifference) and they have been rock solid since.

Worked out of the box
Beware that there is no documentation, and the relays operate when their associated control pin is driven to ground, not when it is driven high. I didn't realise this at first and assumed the unit was faulty. It isn't. Its a good system because it draws very little current from the associated microcontroller.

Handy automation with Raspberry PI
It comes with a handy little screwdriver for the screws on the unit. That was a nice touch. I use it with my Raspberry PI's to automate everything and anything I want and it has never let me down. I will purchase more when I need them. I would recommend this one's.

Perfect for any application
Very good relay module. Have been using it with esp32 to switch lamps and ceiling lights. I use it very often and so far it’s still switching. I’m not sure why others say it breaks. Mines been fine. Comes with a tiny screwdriver for the terminals. All in all, it’s perfect.

Easy to switch on any device using a microcontroller
I brew wine in a shed at the bottom of the garden, and I used this device to automate the the process using a microcontroller. I monitor the temperature of the demijohn and switch a heating pad on and off in order to keep the brew within its optimum range, and I monitor the noise of the bubble trap so that the Arduino can switch on a light in the shed window when it has finished fermenting. It saves a lot of running up and down the garden to check how it's doing. 🙂
