Good relays
These work well, my only criticism is that the AC/DC output ports names are all in Chinese! From left to right I have them wired as Ground | Common | Live.I have them switching 6 amp 240VAC and 6v DC with no issues.

Great value, works as expected.
Great product, works as advertised and expected.Doesn't need to be used with Arduino, we use them standalone.Very flexible.

Half works - not the important half unfortunately
Window to return has passed as I started this project later than planned but thought I could help some others: the lights to indicate on and off are all working but the relays themselves are not clicking into action

Very bad quality product!
The terminal screw are very bad quality!

Ground Triggered
The units trigger on ground not on 5V which is misleading based upon the product description. For a ground-triggered relay, they worked perfectly well but this is tricky with an Arduino - +5V trigger is preferred.

Responsive relays.
Works without issues, these relays are very responsive. Will buy again.
