Buzzer itself works as it's supposed to. And I like black PCB :)
I couldn't get this thing to work the way pins are marked, then I figured out that GND should go to pin marked as "S", and Arduino's PWM signal goes to pin that is marked as "-".
Works with Arduino, just reverse pins as described in cons.
I think I could have possibly found a better deal if I had bought buzzer without PCB because I see some here in DX that are 1.5EUR for 5 pieces.
Sound is a bit squickier compared to buzzer that I took from some old clock, but it works fine.
