The battery cover fits perfectly accurate. Nothing wobbles, creaks or is over. Also the rubber ring for water resistance is present. Original part precisely. Over black cap, with my S5 equipped, the blue cover is not so handy. He feels a bit "smoother". The color can vary depending on lighting, or type of light source, vary and fluctuate between the blue on the product photo and a kind of green-turquoise. I can live well with the color.
