I took my Aqueon for a dive at Porteau Cove on February 23, just a few days after receiving it via courier.
I was very excited to be using it for the first time but there were a number of things that I had to relearn:

Only the slightest knee bend is required for the best amplitude of the fin
Forward surface dives are very difficult. A back start is best for heading straight down from a dead stop
Below is a video that I compiled from this first experience:
