Oristo,
I picked up a bridge from the eBay link above. The build quality is poor and the 2, 100 ohm resistor pairs are each not in parallel. So even though the board is green, it's no better than one of those blue boards with the same issues.
At least it's fixable.
I've attached a couple of photos.
