The flap we found by chance because I've actually always been looking for specific brand, this flap is identical to the original target, but it costs less than half. Lock function as expected, a little shaky, therefore only suitable for brqave / lazy cats. The volume during opening and closing is different, we have built 4 pieces, 2 are quietly and easily opened, the other rattle or remain ever open. Overall value for OK quality acceptable.
