Generally weak springs. In the last two weeks my phone has fallen out of my belt at least 6 times and my phone has fallen out of the clip at least 4 times. The middle clip is too wide. I can't get my phone out without pressing the external buttons on my phone. If the springs were stronger and the center clamp wasn't so wide I think you would have a great product.
