I returned mine. The soldering was poor and the whole thing seems poorly assembled.Hope that helps!

It works for a little while well but starts to leak power as it gets used more.

When hooked to 120V AC to switch a load, in the off state, they leak voltage instead of being at 0V AC. This may be fine for some loads, but not for others. I was switching a tiny power supply and other electronics at 120V AC but each load was between 100ma and 300ma and noticed that in the off state the electronics was flickering instead of being off.Replaced this unit with a more traditional style and no more flickering. Off should mean off but this unit doesn't understand that.

I used this as part of a relatively unique project. When I was remodeling my house I installed a cheap(ish) hood fan. One of the buttons broke and when I went to repair it I learned that they had made it basically impossible to repair as is without rebuilding the entire thing... CHALLENGE ACCEPTED. The switches in it were ALL mains voltage and the fans all returned to a common neutral, so I figured I would program a microcontroller to operate solid state relays to close the circuits from input from momentary switches (the space from the original switches only allowed me to fit something

This replaces my earlier review, because I just recently learned that this type of SSR cannot switch a DC load. They *only* work with AC loads. It is mentioned in the product page but unless you were already aware of this being an issue with solid state relays, the note could be easily overlooked or misinterpreted. It's because they're not really relays in the sense that mechanical relays are - the switching function is emulated using triacs. If the current is not AC the triac can never switch off.Note also: although the relays can be triggered by 3.3V GPIO signals, the device itself has to be powered by 5V; unlike many of the mechanical relays I've used which would work off a 3.3V supply.It turns out that for switching a light DC load all you really need is a much cheaper Optocoupler such as https://www.amazon.com/gp/product/B0BBQW62HQ/

This item worked perfectly for my use as a bi-directional AC motor control with my Raspberry Pi. I would have loved documentation but I was able to figure it out with little tinkering.

This is a fine device, but it won't work for my situation. I need to be able to control a 12V load with a 12V trigger. This can't do that. When the relay is triggered, it only lets 1-1.2V through, even with a 12V 5A load.
