    does what we expected

works like we want. Thanks

    Does what it says, but room for improvement
  

*by C***S on Reviewed in the United Kingdom on 18 August 2023*

Did exactly what I needed to do, right out of the box. Only too a few minutes to find example Python script to get me started.Two ways it could be improved.1. The screw connectors feel a little flimsy. Im sure they're fine and it wont be a problem, but I was aware they might not be the best.2. This hat only uses 4 GPIO pins, but its not stackable, so if you wanted to use any other of the GPIO pins, you'll need to get the soldering iron out. This is *really* irritating. I want to put and LCD display HAT over the top to display the status, but i cant. Infact I cant do anything with the pins unless i solder the stuff on. Please fit through headers in future.On the whole its a good price, and does what is advertised. Would happily recommend with the caveat in point (2)

    Just works
  

*by C***D on Reviewed in the United Kingdom on 30 October 2022*

Nice and easy to fit relay Hat. I control it via sending terminal commands from a windows pc to change the relay state. My only criticism would be that you cannot stack another Hat on top of this unit as the gpio pins don’t extend for another connection. The relays do make a nice clunk sound so you can tell if they are working.
