Hi, I've been using the Virb Ultra 30 for about 5 months now and I like it. The sensors are tend to lag sometimes at the beginning of the jump, I'd say for about 5 seconds or so. But Later on when you lay out the sensor data on the video it helps a lot to analyze the tracking dives and ws. Also I love the flip switch to start and stop recording = "is my camera on??" no more! All in all - I recommend.
