Purchased a groupon for gender reveal with the 3D 4D HD combo. Specifically because of the 3D 4D HD. They never switched from 2D. When we asked about switching to 3D the ultrasound tech asked why we wanted to see it. "It looks like a creepy alien" yes we want to see our creepy alien. That's why we just paid $65! This is our 3rd kid and we have done this many times and have never had our unborn child insulted by an ultrasound tech. She didn't seam confident about the gender and explained what she was looking at but we have sat through more than a couple gender reveals both our own, and a number of friends and family members and never heard it explained like this. We are not confident about it. We feel ripped off. They tried to sell us on all the other stuff in the shop and told us to come back when we are ready to do 3D. That's what we just paid for! My wife cried most of the way home.
