Works as it should. There's only light for when relay is active (not if there's vcc is on, too. But that's just a detail)

Rock solid. I ordered bunch of stuff. 2 of arduino mega 2560 R3, relay boards, ultrasonic sensor etc.
Everything works perfectly. I got expedited shipping and I got from China in 2 days!
Only complain is that USB cable is kind of short. Not possible to move the board around laptop when connected, but thats a small complain for this price.
