Header pins alignment
Great arduino clone. No programming issues.The only reason i gave 4/5 is the fact the the header pins were not 100% aligned, thus making it hard to couple with the Uno board.

Documented and easy to use
It is not obvious how to connect this to a Raspberry Pi but it works well with an Arduino Uno and a sample program is available.

Works great unless your have an Ethernet shield.
I am using this shield with an original Aduino uno R3. The shield works just fine with the Uno alone. However if you have an arduino Ethernet shield like in my photo. Relay number 1 uses pin 4 which is used by the Ethernet shield. Thus I had to remove the pin and soldered pin 4 on the relay board to pin 8 as that is available. Pins 5 6 7 are used by the other three relays. I hope that they revise the plan so that this would not be a problem in the future though I highly doubt it but I did send keyes a note and they did acknowledged me. Other than that it works just fine for my applications.
