Nice one-afternoon project. It works well, as expected. It is very practical and very good value for money. It comes with no instructions, but none are needed as the silk screen on the printed circuit board is very clear. There is a mistake in the description section on this item's page: it says that jumper 2 (JMP2) should be set over pins 2 and 3 for the relay to work; it is actually the reverse: set JMP2 over pins 1 and 2 and the relay will be activated by the photoresistor, while setting it over pins 2 and 3 bypasses the relay.
