It helps me track my website speed in real-time, which was very helpful for our team as we were able see where improvements needed improving so it's great! I've had some issues when updating but they have been resolved quickly by their support staff - really good customer service too!! Make sure you know what kind or type your hosting plan has because not all plans are created equal (we used shared). We found using dataponetwork helped us improve site speeds dramatically even though there isn't anything wrong at first glance about them looking after customers well enough :).
